As a kind of corundum, sapphire has the characteristics of high strength, high hardness, high temperature resistance, corrosion resistance, good wear resistance, small friction coefficient and high resistivity. In addition, sapphire also has good thermal conductivity and electrical insulation. The most important thing is that sapphire has good light transmittance in visible and MWIR bands, which is often considered as the ideal material for infrared military equipments and satellite optical windows.
Due to the characteristics of sapphire, the transmission range of polished sapphire is from 170nm to 5.3μM. It has the characteristics of high strength, high hardness and high chemical stability. Its strength is five times of that of glass, and it is resistant to high temperature up to 2000°C.
The superiority of sapphire windows attribute also determines its wide application range. The polished sapphire glass can be used as sapphire optical windows, lens protector, window, armored window, wear-resistant window/optical element, optical window having resistance of high temperature and impact, etc. Sapphire glass with high quality is usually a kind of parallel plane plate, which is usually used as the protective window of electronic sensor or external environment detector.
When selecting the window, the user should consider whether the transmission properties of the material and the mechanical properties of the substrate meet the application requirements. The window slice does not change the magnification of the system. As a professional supplier of sapphire windows, Cryscore Optoelectronic Limited will provide you with sapphire windows of various sizes and thicknesses. Welcome to select and buy.
