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:

Sapphire glass cover of applications

• - For LED substrate 
• Sapphire wafer and substrate applications include:
• - Microelectronic IC applications - SOS Silicon-on-Sapphire
• - Growth of superconducting compounds / Gallium Nitride - Infrared detectors
• - Hybrid microelectronics - Polishing carriers
• Hostile environment
• Optical transmission from ultraviolet to near infrared
• High temperature Radiation resistance
• aslike watch glass, scanner protect windows, lens, camera cover
