Applications
Sapphire glass/ruby glass has excellent thermal, electrical, and dielectric properties, as well as chemical corrosion resistance. It is resistant to high temperatures, has good thermal conductivity, high hardness, infrared transmission, and good chemical stability. Therefore, it is commonly used to replace other optical materials in the production of optical components and infrared transparent optical windows, and is widely used in infrared and far-infrared military equipment, such as night vision infrared and far-infrared sights, night vision cameras, and other instruments and instruments for satellites, space technology, as well as windows for high-power lasers, various optical prisms, optical windows, UV and IR windows and lenses, and observation ports for low-temperature experiments. It has been fully applied in high-precision instruments and instruments for navigation, aerospace, and aviation.
