Sapphire is used for windows in 190-4000nm wavelength range. Sapphire windows exhibits the unique capability of having a broad transmission range and high optical transmission: from the vacuum ultraviolet to the IR spectrum. It is recognized as a highly important optical material because sapphire combines high transmission with outstanding mechanical-strength properties at high temperatures. Sapphire windows are widely used as protective windows. Sapphire windows are ideal for applications where high pressure, vacuum, or corrosive atmospheres are a consideration. Sapphire windows will exceed all other optical materials in harsh environments, providing a better barrier between elements. |
