Nozzle Gem Core

Since high-quality artificial sapphire/ruby crystal materials have good light transmittance in the 0.20~5.50μm band and the infrared transmittance hardly changes with temperature, optical components and infrared optical windows made of high-quality artificial sapphire are fully used in military night vision infrared equipment, low-temperature laboratory observation ports, and high-precision instruments for navigation, aerospace, etc.
