Germanium Window

   Germanium (Ge) single crystal is a chemically inert material with a transmission spectrum range of 2 - 12um, a commonly used infrared optical material with high hardness, good thermal conductivity and insoluble in water. Widely used in infrared imaging systems and infrared spectrometer systems, germanium single crystals have good mechanical and thermal conductivity and very little absorption at 10.6um, making them ideal for CO2 laser lenses, windows and output coupling mirrors.

   When used as window glass, they can be coated as required to increase the transmission in the corresponding wavelength band. Three types of coat range 3-5um, 8-12um, 3-12um.
