Germanium single crystal window plate

Germanium (Ge) single crystal is a chemically inert material with a transmission spectrum ranging from 2 to 12μm. It is a common infrared optical material. It has the characteristics of high hardness, good thermal conductivity and insoluble in water. It is widely used in infrared imaging system and infrared spectrometer system. Germanium single crystal mechanical properties and thermal conductivity is good, in 10.6μm absorption is very small, with germanium single crystal processing window is CO2 laser, can also be used to make a variety of filter substrate ■ Germanium in infrared optical applications, mainly used to manufacture infrared optical lens and infrared optical lens protection of the infrared optical window. More than 60% of the middle and low end infrared optical lenses are made of germanium single crystal, and 50% of the infrared optical lenses are made of germanium single crystal. Germanium materials are widely used in infrared lenses. In the civil infrared lens, the germanium consumption of small and medium caliber lens is about 250 grams, and the large caliber lens is about 2500 grams. ■ Infrared window is mainly used in aircraft and armored fighting vehicles, especially helicopters. The application of infrared optical lens includes military application and civil application. In military, it is mainly used in airborne infrared lens, shipborne infrared lens, roadbed infrared lens, vehicle infrared lens, infrared lens, helmet infrared lens, handheld infrared lens and so on. ■ Civil infrared window is mainly used in a variety of monitoring thermal imagers, night-time auxiliary pilot. The civil field is mainly used in security, civil vehicles, civil ships, civil aircraft, etc.
