There are sapphire plane optical windows (maximum diameter 220mm (round wafers) or 300mm (square wafers). Sapphire optical windows are widely used to replace other optical materials optical element, infrared optical window,and they are used in infrared and far infrared military equipment, such as instrument used in night vision infrared and far infrared sight, night vision camera instruments, satellites, space technology, high power laser window, optical prism, optical window, the UV IR window, lens, low temperature observation, aerospace navigation,etc.
Typical application
Gas and air analyzer / monitor
Integrated circuit substrate
Violet / infrared detector
Epitaxial substrate
High-pressure window
Barcode scanner
