Overview
Since the high-quality artificial sapphire/ruby crystal material has good light transmission in the 0.20~5.50μm band, and the infrared transmittance hardly changes with temperature, optical elements and infrared-transmitting optical windows made of high-quality artificial sapphire , It has been fully used in military night vision through infrared equipment, cryogenic laboratory observation port, high-precision instruments and meters for navigation, aerospace and aviation.
