Sapphire (Sapphire, also known as white sapphire, molecular formula Al2O3) single crystal is an excellent multifunctional material. It has high temperature resistance, good thermal conductivity, high hardness, infrared transmission and good chemical stability. Widely used in many fields of industry, national defense and scientific research (such as high-temperature infrared windows, etc.).
Sapphire window are widely used in infrared and far infrared military equipment, such as night vision infrared and far infrared sight glasses, night vision cameras, and other instruments and meters in satellite and space technology, as well as windows for high-power lasers, optical windows, UV and IR windows, and observation ports for low-temperature experiments. It has been fully applied in high-precision instruments and meters for navigation, aerospace, and aviation.
