    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.


    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
