The transmittance range of optical germanium material is 2-14um, and its refractive index is as high as 4. Germanium lens and germanium window are widely used in thermal imaging system. Because germanium material has high refractive index, the surface reflectivity is very high (R>30%), so optical germanium elements usually need AR coating.
Germanium optical performance is severely affected by temperature; the transmission rate decreases with the increase of temperature, most applications with Germanium elements involved can only be applied below 100 degrees Celsius. Designers also need to pay attention for certain weight constraints in system design with a density of germanium (5 ...
