V8.14.113

Core

It is now possible to import the unit definitions from one materials database to another. From the Tools menu, select General Units (this option will only be available when there are no open windows on the Essential Macleod desktop). Click on the Import button. Select the materials database containing the units you wish to use and then click on OK. The units will be updated with the units in the selected materials database. Click on OK to save the units to the current materials database.

You can now easily switch between a contour plot and a perspective plot for 3D plots. With the cursor in the 3D plot, right-click with the mouse. If the plot is currently a perspective plot, there will be an option labeled "Contour Plot". Selecting this will change the plot to a contour plot. If the plot is currently a contour plot, the option will be labeled "Perspective Plot", and selecting it will change the plot to a perspective plot.

Change History

The formula syntax has been upgraded so that thickness multipliers outside brackets are applied to layers inside the brackets. For example 2.3(HL)^3 would be interpreted as (2.3H 2.3L)^3 and 1.1(A 2.3(HL)) would be interpreted as 1.1A 2.53H 2.53L.

A coating machine will typically show a variation in deposited thickness across the area where parts may be coated The variation depends upon the location and form of the material sources and so the magnitude and variation will typically be different for each material source. In the coating machine (when properly calibrated and neglecting production errors) there will a location where the manufactured part will have the designed thicknesses. We will call this the Reference Location. Parts at some distance from this reference location will have thicknesses that are not the designed thicknesses caused by the non-uniformity of the coating machine. This will cause changes in the performance of the design. The Essential Macleod provides a simple one-dimensional linear model of uniformity that allows the impact of non-uniformity to be investigated. Each material has a Taper Factor parameter. In uniformity calculations, a Taper Distance is specified. During the performance calculation, the thicknesses of the design are modified as follows:

NewThickness = Taper Distance * Taper Factor * Layer Thickness

Where Taper Distance is in arbitrary units.

Taper Distance may have negative as well as positive values. Taper Factor may also be positive or negative. Uniformity calculations are available in 3D plots (choose Taper Distance for the x or y parameter) and in Active Plots for Designs (add the Taper Distance variable).

The color patch that may be generated during color calculations can now be copied to the clipboard and pasted into other documents. To copy the color patch, either select Copy from the Edit menu, or with the color patch window active, press Ctrl-C on the keyboard.

There are now two types of license available: a Transferable License or a Fixed License. A transferable license can be moved from one computer to another and has, up to now, been the only type of license available. A fixed license cannot be transferred from one computer to another, but you can make a backup copy of the license. A fixed license is only available for certain computers. Availability can only be determined after the key request has been made.

A Fixed license can be backed up to a separate location and restored to the computer in the event that the license data is lost. Also a fixed license is not sensitive to disk defragmentation whereas the transferable license must not be moved from its original location on the disk.

With the Essential Macleod running and no windows open on the Essential Macleod background window, select License from the Options menu. Then click on Backup License (Backup License will only be available if you have a fixed license). A folder chooser will appear. Select the folder where you want the license to be saved. This can be a location on your computer, removable storage or an


Change History

accessible network location. Click on OK. A message will state that the license has been successfully backed up.

If the license is not present, you will see the Limited License message when you start the Essential Macleod. Click on the Restore License button. A folder chooser will appear. Select the location of the backup copy of the license and click on OK. When the license is successfully restored, the Essential Macleod will start.

Function

The PlotCreator object can now set the plot to be a regular Cartesian plot or a polar plot. To set a polar plot use:

MyPlotCreator.PlotType = PolarPlot

To set back to a Cartesian plot use

MyPlotCreator.PlotType = CartesianPlot

The default type of a plot is CartesianPlot.

The definitions of PolarPlot and Cartesian Plot are contained in a new set of script files. Please contact Thin Film Center ([email protected]) to get the latest script files.

A Help button has been added to the Script Manager. Selecting a script and clicking on this button will cause the pdf file with the same name as the script to be displayed. This requires that a pdf reader is already installed on the computer.

V8.13.76

Core


Change History

A Report Generator has been added. This feature allows you to control the data that is included in printed reports. A report template controls the data and formatting of printed output. Default templates in the current materials folder can be used to control the output when the Print command is used. Other report templates can be used by selecting the Print Report or Preview Report command. With these commands, you can select the report template to be used. For more information please see the Report Generator chapter in the Manual.

V8.12.53

Core


Saving designs to new files after refining in Stack did not work correctly

Substrates with small wavelength intervals were not saved correctly

V8.12.51

Core

A thermoelastic stress model has been added to the Essential Macleod. The stress model calculates the stress in layers due to temperature changes as well as curvature and substrate deflection. Details of the model can be found in the Analysis section of the manual.

Back Reflectance has been added to the set of performance parameters that can be calculated in Designs. For non-normal incidence back reflectance calculations, the incident angle specifies the angle of the beam in the substrate. This applies to Back Reflectance targets for refinement and to back reflectance calculations in Stack.


Change History

V8.12.41

Core


On some computers, color calculations did not work.

Target plotting for Density did not work

Calculating a table, closing the table and then calculating a table again caused an error

V8.12

Core

An inhomogeneity model has been added to the Essential Macleod. Inhomogeneity is represented by a single parameter (Inhomogeneity Factor) that specifies the total change in refractive index from the front to the back of a layer as a proportion of the refractive index of the material (including packing density effects) of the layer. For example if the refractive index of the layer is 1.3 and the Inhomogeneity Factor is 0.1, then the layer is inhomogeneous with the refractive index at the incident medium end of the layer being 1.235, and the refractive index at the substrate end of the layer being 1.365. Use File->Display Setup in the Design window to show the Inhomogeneity Factor column. The inhomogeneity factor is due to Abeles.

Color Rendering Index calculations have been added to the Essential Macleod. Color Rendering Index can be used both as performance parameter to be calculated and as a parameter for refinement.

Edit Sources and Edit Observers (programs used to defined sources and observers for color calculations) have been integrated into the Essential Macleod. Select General from the Options menu and click on the Sources and Observers tabs to maintain the lists of Sources and Observers.


Change History

Simulated Annealing refinement now includes linked layers.

Physical Thickness constraints have been added for refinement. Each layer in a design can have a minimum and maximum physical thickness specified. To see the thickness constraint columns, Select Display Setup from the File menu of the Design window. Check Minimum Physical Thickness and Maximum Physical Thickness and then click on OK. You can now enter thickness limits for each layer.

The trace editor for plots now includes a Swap Axis button. When a trace is pasted into an existing plot, it is always plotted with respect to the first Y-axis. Using the trace editor, you can now change a trace so that is plotted with respect to the other Y-axis, A trace plotted with respect to the first Y-axis will be plotted on the second Y axis after clicking on Swap Axis. A trace plotted with respect to the second Y-axis will be plotted on the first Y axis after clicking on Swap Axis,

Designs can now be exported to the FRED optical modeling software produced by Photon Engineering. To export a design, select Fred from the Export sub-menu of the File menu of the Design window.

Material and Substrate Import now includes the ability to automatically include the corresponding Substrate/Material, when a Material/Substrate is being imported. The Material and Substrate must have the same name for both items to be imported. This saves you having to remember to import the substrate definition after importing the material or vice versa.

The Material and Substrate import dialogs now give you more information about the material being imported. The Import Material window shows the optical constants for each material and you can also plot the optical constants by using the Plot buttons to the right of the materials list. The Import Substrates window allows you to plot the internal transmittance of a substrate by using the Plot buttons to the right of the substrates list.

The list of materials databases can now be maintained. Select General from the Options menu and click on the Data Sources tab. Click on the Maintain Folders tab. The Maintain Materials Folders dialog will appear. You can change the order of the folder list, remove folders from the list and add folders to the list.

Reverse Layers now will reverse just the selected layers in a design. Previously Reverse Layers always reversed all layers in a design regardless of whether some layers were selected or not.

Runsheet

Runsheet now plots the monitoring curves for each source in user defined colors. The colors to be used are specified in the machine configuration file in the Line Color column window of the Sources tab.

Function


Change History

A Stack object has been added to the objects available in scripts.

A ReferenceFolder function has been added to the Session object for scripts. This allows you to determine the location of the Reference folder from a script.

Scripting now supports running a menu command from inside a script. The objects now provide a RunMenu function that executes the specified menu command.

The following scripts have been added:

Create CCT Illuminant

Performance with Illuminant

Figure Error

Run these scripts to see a description of the calculations that they perform.

V8.11.38

Core

The following errors have been fixed:

Notes could not be added to tables or references. Using Edit Materials when some layers were selected gave an error.

Runsheet

Add Material Refractive Index and Design Thickness columns to the Runsheet. These columns are not displayed by default. To see the columns, use Display Setup in the File menu.



Change History

On some computers, Runsheets could not be opened by version 8.11.32. Active plotting did not always operate correctly when multiple chips were used in a Runsheet.

V8.11.37

Core

Added the ability to control the line styles used when traces are added to a plot. The default plot styles (Options menu -> Chart Styles) control the appearance of the first trace on the plot. When traces are added to the plot, the line style is changed so that the traces can be distinguished. After several traces have been added, the dotted line style will be used. This line style can often be difficult to see. The default plot styles form now includes the ability to stop the use of the dotted (or other line styles) when traces are added to the plot. To use this feature, check the line styles that you want to be used and uncheck the line styles that you do not want to be used. Note that the default plot line style does not have to use a checked line style.

The following error has been fixed:

Pasting or adding rows in the Target editor did not properly update the screen if target links were used..

Runsheet

Added the ability to format the data in the Runsheet. To set the formats, select Runsheet from the Options menu. Now select the Runsheet tab. The formats for the various types of data presented in Runsheet can be controlled here.


On some computers, Runsheets could not be opened by version 8.11.32. Active plotting did not always operate correctly when multiple chips were used in a Runsheet.


Change History

V8.11.32

Core

The following error has been fixed:

Designs that were used in Stacks did not always update the Stack when the Design was edited.

Added Export command for the Sigma Instruments SQC Series Comm program. This permits designs to be uploaded in the Sigma Instruments monitor.

Runsheet

Added Display Setup command to Runsheet. The displayed columns in a Runsheet can now be controlled by the Display Setup command in the File Menu. This command controls the columns displayed in the Runsheet and can also specify the columns to be displayed by default in new Runsheets by checking the Make Default box. The default displayed columns can also be specified by selecting Runsheet from the Options menu and then clicking on the Display Setup tab. The checked columns in the list will be displayed in new Runsheets.

V8.11

Core

The Errors tool has been updated to allow errors to be specified for each material in the design.

Errors may be specified for both thickness and refractive index for each material in the design. For thickness errors, there are three parameters: Thickness Mean Error, Thickness Standard Deviation and Minimum Thickness. The Thickness Mean Error and Thickness Standard Deviation specify the


Change History

statistical properties of the normal population from which the random numbers for thickness errors will be drawn. For layers that are thicker than the Minimum Thickness, the error will be applied as a proportion of the layer thickness. For example, to apply a thickness error where the standard deviation is 2% of layer thickness and there are no systematic thickness errors, the following parameters are used:

Thickness Mean Error: 0 Thickness Standard Deviation: 0.02 Minimum Thickness: 0

In this case the thickness including error will be calculated as

ErrorThickness = LayerThickness + LayerThickness * RandomNumber

Another case is to apply an absolute error to the layer thickness that does not depend upon the thickness of the layer. For example, to apply a thickness error where the standard deviation is 2nm the following parameters can be used (providing no layer is thicker than 1000nm):


In this case, the thickness including error will be calculated as:

ErrorThickness = LayerThickness + MinimumThickness * RandomNumber

With the values above, the standard deviation of the amount added to the layer thickness will be 1000 * 0.002 = 2 nm.

A combination of proportional and absolute errors can be achieved by correct setting of the minimum thickness. For example, to specify 2% thickness errors with a minimum thickness error standard deviation of 2nm, the following parameters would be used:


For layers thicker than 100nm, the thickness error will be calculated as

ErrorThickness = LayerThickness + LayerThickness * RandomNumber

For layers thinner than 100nm, the thickness error will be calculated as:


Change History

ErrorThickness = LayerThickness + MinimumThickness * RandomNumber

For layers thinner than 100nm, the standard deviation of the amount added to the layer thickness will be 100 * 0.02 = 2 nm

For refractive index errors, there are two parameters: Index Mean and Index Standard Deviation. The Index Mean Error and Index Standard Deviation specify the statistical properties of the normal population from which the random numbers for index errors will be drawn. For refractive index errors, the random number is added to the packing density of the layer to generate the perturbed refractive index for the layer, i.e.

ErrorPackingDensity = Packing Density + RandomNumber

Two new sensitivity tools have been added: Independent and Distribution. The Independent error tool shows a bar graph of the sensitivity of each layer to changes in its thickness or refractive index. The Distribution tool shows how the merit figure of the design varies as each layer is moved from its nominal value.

The Independent sensitivity analysis is a Monte Carlo method of assessing the sensitivity of each layer to thickness or refractive index errors. The tool generates a set of designs with errors according to the supplied error parameters. The merit figure of each design is calculated (using the refinement targets) and normalized by taking the Merit Function Power’th root of the merit figure (the Merit Function Power is specified in the refinement parameters). The tool then plots, for each layer, the difference between the upper quartile merit figure and the lower quartile merit figure. The larger this number, the more sensitive the layer is to errors.

The Distribution sensitivity analysis displays the variation of the merit figure as each layer is varied in thickness or refractive index. The size of the variation is determined by the error parameters. These are the same parameters as used in the Errors command For each layer the error term is varied from –2 standard deviations to +2 standard deviations. This range is divided into Number of Steps intervals. For each point the Merit Figure is calculated (using the current refinement targets) and normalized by taking the Merit Function Power’th root of the merit figure (the Merit Function Power is specified in the refinement parameters). The results of these calculations can be plotted on either a contour plot or a 3D plot

Targets can now be expressed as inequalities. For example, you can now set a target of Reflectance >= 90%. The inequality is specified in the Operator column.

Runsheet

Runsheet can now generate Active Plots. In these plots you can interactively change the tooling factor,


Change History

monitoring wavelength and bandwidth of the layers and see the changes plotted immediately.

Leybold LMR and LDD data can now be imported and exported.

Material dispersion data are communicated in the Leybold Dispersion Data file. This file normally has a .ldd extension. To create an ldd file from an existing material, open the material. From the File menu, select Export and then Leybold LDD… A file chooser will be displayed. Enter the name of the ldd file and click on Save. This will write the material data into the file in the ldd format. The data in an ldd file can also be imported as a new material. To open an ldd file, select Open from the File menu. A file chooser will be displayed. Change the Files of type to All files (*.*). Select the ldd file and click on Open. The ldd material data will appear in a new material window.

Runsheet data are communicated in the Leybold Monitoring Repoprt file. This file normally has a .lmr extension. To create an lmr file from an existing runsheet, open the runsheet. From the File menu, select Export and then Leybold LMR… A file chooser will be displayed. Enter the name of the lmr file and click on Save. This will write the runsheet data into the file in the lmr format.

The data in an lmr file can also be imported into the Essential Macleod. The lmr file contains material data and the design. To open an lmr file, select Open from the File menu. A file chooser will be displayed. Change the Files of type to All files (*.*). Select the lmr file and click on Open. The Leybold Monitor Report window will appear. From this window, you can open the materials and design contained in the file.

Function

A Table object has been added to the scripting language. This allows you to manipulate tables, and interpolate values from them.

Tables did not automatically show fractional wavelengths when the locale was not US-English.

Designs loaded from the Synthesis History did display the correct Reference wavelength and Incident Angle.

V8.10.51

Core


Importing substrate reflectance without importing substrate transmittance caused an error when attempting to derive optical constants.

A check box "Auto Add" has been added to the Transmittance and Reflectance displays of the Optical Constants tool. When this is checked, the Add Point button is automatically clicked after a region has been selected for peak finding. If it is unchecked, the Add Point button must be clicked to add the data point to the table.

Conjugate Refinement ignored the update interval.

Design notes were lost during refinement.

Function

The DataSet, Admittance and ElectricField objects now have interpolation functions.

V8.10

Core

The behavior for opening Designs, Materials and Substrates has changed. Previously if you opened the same design twice you see two separate copies of the Design. Now when you open two copies of the same design, you will still see two windows, but they will share the same data. If you change something in one design window, it will also be changed in the other design window. This also applies to designs opened by a script (see Function below). If a script opens a design that it is already open in a design window, the script will modify the design that already open in the design window. This behavior also means that you can now see the effects of changes to changes to materials, substrates and designs in other windows that use them without having to save the material/substrate/design first.

Open a Copy Of command has been added to the File menu. Open a Copy of loads the selected file into a new window. Open a Copy Of does not retain the filename from which the data was loaded so when you save the file, you will be asked for a filename in which to save the data.

You can now calculate the color of a spectrum in a table. Select the column in the table and then click on Color in the Tools menu.

It is now possible to delete any material or substrate in a Materials database. Select the Material (or substrate) to be deleted and then click on Delete in the Edit menu. You can also undelete deleted materials and substrates. Use the Undelete command in the Edit menu to see the materials that can be undeleted. Creating a new material will completely remove one of the deleted materials so you cannot rely on a material always being in the deleted material list.

The thickness restriction in the Symmetrical Periods design tool has been removed. The tool will also provide alternative solutions where they exist.


Change History

A Design can now be exported to a Code V sequence file. This command is in the Exports sub-menu of the File menu.

The convergence of the Quasi-Newton refinement method can often be improved by restarting the refinement after it has performed several iterations. The parameter Recycle Interval has been added to Quasi Newton refinement parameters. Quasi Newton refinement will be automatically restarted every Recycle Interval iterations. If Recycle Interval is set to zero, then the refinement will never be automatically restarted.

The behavior for pasting Targets has been changed. Previously, when targets were added by the Paste command or by Generate Targets, any duplicates that were created were automatically removed. If you wanted to paste duplicates and make modifications so that they were no longer duplicates, you could not do this because the duplicates would be removed. You can now control this action so that it is possible to paste duplicate targets and modify them after pasting. To change the behavior, select General from the Options menu and then click on the Targets tab. If Remove Duplicates Immediately is checked, then duplicate targets will be deleted as soon as they are detected. If it is not checked, then duplicate targets will not be automatically removed. A command Remove Duplicates has been added to the Edit menu for Targets. Using this command will remove duplicate targets from the Target window when Remove Duplicates Immediately is not checked.

The refinement methods are now all using Minimum Merit Function Improvement to Update Plot. This parameter which is in Conjugate Gradient and Quasi Newton parameters is now used by the other Refinement methods too. The older methods of specifying when to plot have been removed.

Substrates can now be sorted alphabetically. To sort, choose a sort order from the Sort sub-menu of the Edit menu.

The Import Substrates command now has a browse facility like the Import Materials command.

Function

Function now includes scripting language support.

The Function enhancement now provides the ability to write scripts. The scripts are written in a language that is very similar to VBA (the macro language included with Microsoft Office). Currently scripts can operate on Materials, Substrates and Designs. The Simplex, Optimac and Simulated Annealing methods now support Custom Merit Functions. Custom Merit Functions replace the internal merit function with a user written merit function using the scripting language. Information on the Scripting Language is provided in the Scripting Language help file. To use the help file select Scripting Language from the Macleod program folder (Start Menu -> Program Files -> Macleod -> Scripting Language Help).


Change History

vStack

vStack now calculates the total phase response of all coatings in the vStack. This calculation shows the contribution of the coatings to distortion of the wavefront. Phase changes in the substrates cannot be included in the calculations as the thicknesses of the substrates are not defined.

V8.9.54

The OMS3000 Export did not correctly check the Runsheet data. This has been fixed.

V8.9.50

Core

Optical constant extrema selection did not work correctly when the units were set to absolute. This has been fixed.

Runsheet

A new dynamic tooling factor type has been added to Runsheet. You can now specify a tooling factor to be used for each layer deposited by a source. To use this new tooling factor type, create a 2 column table. The first column is the layer number and the second column is the tooling factor to be used for that layer. The type of the first column must be set to "Layer Number" and the type of the second column must be either "Optical Tooling Factor" or "Crystal Tooling Factor". See the section on Dynamic Tooling Factors in the Runsheet chapter of the manual for more information on creating tooling factor tables. Setting the first column type to "Layer Number" means that the tooling factor will be selected according to layer number, and does not depend on the Dynamic Tooling Convention setting. Instantaneous or Absolute tooling factor tables can be used together with Layer Number tooling factor tables in the same Machine Configuration.

The performance of the monitor wavelength search function has been improved.


Change History

V8.9.47

Core

The Macleod Turning Point Sensitivity calculation did not work correctly. This has been fixed.

Optical Constant Extraction did not print the table of extracted values. This has been fixed

Tables were not displayed correctly in the German locale. This has been fixed.

The global editor for Stacks did not work correctly. This has been fixed.

The global editor for Designs did not use the correct optical thickness convention. This has been fixed.

Locked layers were not recognized by Needle synthesis. This has been fixed.

When changing materials using the Edit Materials command, the optical thickness of the layers will be held constant if the optical thickness column is displayed otherwise the physical thickness will be held constant. Previously the physical thickness was held constant.

When pasting designs from external sources, the thickness convention used now depends on the displayed thickness columns. If the optical thickness column is visible, optical thicknesses will be used. If the physical thickness column is visible and the optical thickness column is invisible, then physical thicknesses will be used. If only the geometric thickness column is visible, then geometric thicknesses will be used.

Runsheet

The exported CSV file now includes the refractive index of the monitoring wavelength at the end of each row.

There is now an Absolute mode for Dynamic Tooling Factors as well as the original Instantaneous Mode. In the Absolute mode, the tooling factor is given by the value in the tooling factor table. In the Instantaneous mode, the tooling factor is given by integrating the instantaneous tooling factors in the table as described in the manual.

To set the Dynamic Tooling Factor mode, select Runsheet from the Options menu, select the Runsheet

tab and set the mode as desired.

V8.9.43

Core

After opening a design, the Optical Thickness was always displayed. This has been fixed.

Two new Design display options have been added. Designs can now also be displayed with the Medium at the top, but layer number 1 is next to the Substrate and also displayed with the Substrate at the top and layer 1 next to the Medium.

When a design was displayed with the Substrate at the top, Copy Design put the same thickness value in all the thickness columns. This has been fixed.

Navigation in the tabular displays has been improved. If a cell is being edited, pressing an arrow key, enter key, or tab key will now complete the edit and move to the next cell. Previously this action took two key presses.

Plots can now have automatic intervals. You can now set a maximum and minimum value and leave the plot interval blank. When you plot, the software will automatically choose an interval.

When making changes to the Link column in the Design editor, the column was not always refreshed correctly. This has been fixed.

Error messages displayed by the Generate Rugate tool sometimes were repeated for each layer in the Rugate. They now only appear once.

V8.9.35

Core


Change History

The Compact tool did not remember the thickness convention. This has been fixed.

Sometimes an "Internal Error 124" would be displayed on starting the Essential Macleod. This has been fixed.

Optical Constants files with spectral data that had a magnitude scale of 0..1 did not save correctly. This has been fixed.

Reference Files did not load correctly in Locales where the "." (period) was not the decimal point. This has been fixed.

V8.9

Core

Contexts have been added to Designs. Contexts support the concept of Agile Materials. An Agile Material is a material that changes its optical constants as a result of some external stimulus (for example an applied voltage) For each Agile Material the context specifies the optical constants to be used. As well as creating designs that use materials that do actually change optical constants due to some external stimulus, this feature can be used to create designs for use on more than substrate or where different materials can be substituted during manufacture.

Color calculations now support Dominant Wavelength (Wd), Complementary Wavelength (Wc), Excitation Purity (Pe) and Colorimetric Purity (Pc).

Color calculations can now show a color patch that displays the approximate color of the coating. If the color calculation includes an incident angle variation, this variation will also be shown on the color patch.

Support for checking for updates to the Essential Macleod has been added to the Essential Macleod. A command in the Help menu – Check for Updates contacts the Thin Film Center web site and looks for updates to the Essential Macleod. If there is a new update, you can then click on the Download button to retrieve the update and apply it to your computer. The General command in the Options menu has a new tab – Update. Here you can specify an automatic check for updates.

In some versions of Windows (particularly Far Eastern versions) files could not be saved in folders with names using characters not in the English alphabet. This version of the Essential Macleod will save files in those folders, providing Internet Explorer 4.01 SP2 or later is installed on the computer. If Internet Explorer is too old, then the Essential Macleod will not save to folders with names containing characters not in the English alphabet. Click on About the Essential Macleod in Help menu. If the version of Essential Macleod ends with "(ie)", then it will work with all folder names otherwise the previous restrictions still apply.


Change History

There were still problems with using the Essential Macleod on computers that did not use . (period) for the decimal separator. This has now been fixed. You can change the separator back to the normal character (typically , (comma) in Europe) and continue working.

Derivatives are now calculated analytically (previously numerical methods were used). There is now only one Wavelength Delta Factor. This is used to calculate the first derivative of the optical constants.

If thermal data are missing when a calculation that requires thermal data is being performed, then a warning will be displayed.

The Stack now supports Gaussian beams in its cone calculation ability. A Gaussian beam can be specified by its semi-angle or its spot size. Although a Gaussian beam has no limit, you can specify a cut-off for calculations. This helps to speed up calculations for a small trade-off in accuracy. The cut-off is known as the Gaussian calculation scale factor. The angle range of the calculations extends to the product of the Gaussian calculation scale factor and the Gaussian semi-angle. The scale factor can be found on the Cone tab of the General options. (Options menu -> General). The default scale factor is 2.

A Plot Targets checkbox has been added to the Performance Parameters dialog. When checked, compatible refinement targets will be added to the plot.

The ability to specify more than one maximum bandwidth has been added.

V8.3

Core

The meaning of Tolerance in refinement has been modified. Tolerances are now used to specify the relative scaling of target types. The difference between the target values and the actual value is divided by the tolerance. This allows targets that vary over a small numerical range to be treated with the same importance as targets that vary over a large numerical range by giving the small range target a small tolerance value.

Plots can now have a second y-axis. The plot parameters dialog has been updated to allow you to specify the performance calculated for the second y-axis.

Several enhancements have been made to the plotting capabilities. In the plot parameters dialog, you can select various plot parameters to be included in the legend for the plot. Plot characteristics are now
