1. Comparison of optical window materials

 

   sapphire wafer is  one of the hardest materials, and possesses very good transmission during the

range of visible and near IR spectrum.It is widely used as optical window in infrared and far infrared

military equipments, apparatus and instruments of satellite and space technology, and navigation

and spaceflight,it has some advantagement aslike below:

• Mechanically second only to diamond. One of the hardest and most scratch resistant materials
available. The high modulus of elasticity and high tensile strength make it extremely wear,
abrasion and impact resistant.


• Colorless optical characteristics are superior to any standard glass, with up to a 98.5%
transmission and a transmission window from 190 nanometers in the UV to 5 microns in the IR.


• No solarization in high-radiation systems.


• High dielectric constant and low loss tangent makes it a great electrical insulator and low
loss long wavelength window.


• Thermally very stable. Does not lose any of its mechanical and optical qualities from cryogenic
to over 2000C.


• Thermal conductivity greater than other optical materials and most dielectrics.


• No surface damage and devitrification due to extreme thermal cycling


• Does not sag or slump at very elevated temperatures.


• Highly corrosion resistant. More resistant to corrosive chemicals than most standard hard
materials available.
