A telescope is an instrument that aids in the observation of remoteobjects by collecting electromagnetic radiation (such as visible light

). The rst known practical telescopes were invented in the etherlands

at the beginning of the !"th century# using glass lenses. They found usein terrestrial applications and astronomy.

$ithin a few decades# the re%ecting telescope was invented# which

used mirrors. &n the ' th century many new types of telescopes were invented# including radio telescopes in the ! * s and infrared telescopes

in the ! + s. The word telescope now refers to a wide range of instruments detecting di,erent regions of the electromagnetic spectrum

# and in some cases other types of detectors. The word - telescope - (from the reek # tele -far- and /

# skopein -to look or see-0 / # teleskopos -far1seeing-) was coined in !+!! by the reek mathematician iovanni 2emisiani for one of

alileo alilei 3s instruments presented at a ban4uet at the Accademia

dei 5incei . 6!76'76*7 &n the Starry Messenger

# alileo had used the term -perspicillum-.

Types of telescope An optical telescope gathers and focuses

light mainly from the visible part of theelectromagnetic spectrum

(although some work in the infrared and ultraviolet

). 6!*7 Cptical telescopes increase the apparentangular siDe

of distant objects as well as their apparent

brightness. &n order for the image to be observed# photographed# studied# and sent to a computer# telescopes workby employing one or more curved optical elements#usually made from glass lenses andEor mirrors

# to gather light and other electromagnetic radiationto bring that light or radiation to a focal point. Cptical telescopes are used for astronomy

and in many non1astronomical instruments# including9 theodolites (including transits )# spotting scopes # monoculars # binoculars, camera lenses

# and spyglasses . There are three main optical types9
