Sapphire is used for windows in 250-5000nm wavelength range. It is recognized as a highly important optical material because optical grade sapphire combines high transmission with outstanding mechanical-strength properties at high temperatures. Sapphire windows can be made thinner than alternative crystals thanks to its structural integrity and can operate up to 2030ºC.
Sapphire windows are widely used as protective windows or viewports. Sapphire windows are ideal for applications where high pressure, vacuum, or corrosive atmospheres are a consideration.
