Sapphire has good transmittance in the spectral range of 200nm~5500nm, and its infrared transmittance hardly changes with temperature. The working temperature can reach 1900 ℃, which allows people to use artificial sapphire windows for operation in high-pressure chambers. Therefore, sapphire crystal materials are commonly used to make various infrared, ultraviolet windows, high-temperature observation windows, flow control, etc.
