Sapphire has the characteristic of high hardness, high strength, high transmittance, and high resistance to thermal shock quality factor. With excellent performance on thermal shock resistance and abrasion resistance, it can be widely applied to high speed working photoelectric equipment and intelligent high speed dome camera in airborne, shipboard, space-borne, submarine-based, land-based field.
