Description
Germanium(Ge) Windows for thermal imaging
Germanium is a commonly used far-infrared material. It has a good transmittance in the light transmission range of 2000nm to 17000nm, and it is opaque in the visible light band, so germanium is very suitable for infrared laser applications. The refractive index of germanium is very high. It is an ideal choice for biomedical and military imaging applications, and is often used in infrared thermal systems, laser applications, etc.
