Headwall is a truly unique technologyventure. Founded in 2003 as the result of a management buy-out of AgilentTechnologies' Holographic Grating Operation, the company is a worldleader in the design and high volumemanufacture of optical modules andholographic diffraction gratings.

Continuing the rich engineering legacyof American Holographic, Headwalloffers our extensive base of worldwide customers a range of integrated opticalwavelength solutions with applicationspecific performance.

Headwall Photonics, headquarteredin Massachusetts, is managed by established industry veterans from thetelecommunications and medicalproduct industries. The company iswell funded to capitalize on our world-class, ISO 9001:2000 certified facilitiesand will continue to maintain our leadership in nanotechnology manufacturing for optical applications.

Headwall's planar and aberration-corrected convex/concave gratings

cover a broad spectral range (UV-IR) for applications in

life sciences, analytical, and telecommunications markets. In addition,

we specialize in the alignment and packaging of these gratings to

enable robust spectral modules and integrated solutions for demanding

and/or custom photonic applications.

Headwall is the world’s largestmanufacturer of original holographicdiffraction gratings.

Headwall Photonicsoffers a wide range oforiginal holographicdiffraction gratings.

Our holographic grating operation leverages Headwall’s capabilities

for high quality, high volume manufacturing. We produce our gratings and

spectral modules in a modern 20,000 square foot facility and an expansive

production cleanroom outfitted with the latest in automated equipment.

Our manufacturing excellence results in higher quality products, and the

ability to meet high-volume customer requirements.

• Rapid Prototyping Capabilities

• Collaborative Product DesignServices

• Optical System Expertise (25+ years)

Original Holographic DiffractionGratingsHeadwall discovered that the highestperformance originates from master-ing fabrication techniques. We haverefined our process to mass produceand exclusively deliver “original”gratings. Our novel approach andproprietary technologies result inboth High Efficiency and Low Polar-ization Dependent Loss performancein a single component.

Our flexible holographic techniquepermits the recording of gratings onplanar, as well as spherical/aspheri-cal surfaces without limitation togroove density. We have pioneeredthe development of aberration-corrected concave gratings andcontinue to enhance our designs todeliver the best optical performancewith the fewest components. Webelieve this technology will continueto enable new designs that aresimpler to develop and more costeffective to manufacture.

Key Benefits of “Original” GratingTechnology• Accurate Recording

-High Efficiency and Low PDL

• Environmentally Stable Materials

-Telcordia compliant

• Very Low Stray Light

-Enhanced spectral fidelity and low cross-talk

Precision Spectral ModulesHeadwall also supplies high perfor-mance spectral modules for OEMphotonic applications. Our compactmodules are cost-effective,prealigned optical systems that areeasily integrated into systems to savedevelopment cost and speed time tomarket. Our HyperSpec VS15 is anunparalleled imaging spectrographwith extremely high spectral/spatialresolution, and we offer spectralmodels with both single- and dual-beam designs.

Headwall Photonics offers performanceand manufacturing in holographicgratings that is second to none. Formore information on how we can helpyou with your next design project,please visit http://www.HeadwallPhotonics.comor http://www.diffract.com
