Factory Custom Optical Sapphire Glass Window
Sapphire glass has good thermal properties, excellent electrical and dielectric properties, and chemical resistance. It is resistant to high temperatures, good thermal conductivity, high hardness, infrared transmission, and good chemical stability. Therefore, it is often used to replace other optical materials to make optical components, penetrate infrared optical window films, and is widely used in infrared and far infrared military equipment, such as: applied to night vision infrared and far infrared scopes, night vision cameras and other instruments And satellite and space technology instrumentation, as well as windows for high-power lasers, various optical prisms, optical windows, UV and IR windows and lenses, observation windows for cryogenic experiments, and high-precision instruments and meters for marine aerospace applications.
