Germanium (Ge) in the range of 2-12 μm, germanium is the most commonly used material for making optical lenses and optical windows in efficient infrared imaging systems. Due to the wide transmission range and visible opacity, germanium is very suitable for the manufacture of optical components of infrared lasers and optical systems. The high refractive index and minimal surface curvature of germanium make it ideal for making low-power imaging systems. Poor color, often eliminating the need for correction. The absorption of germanium increases with temperature. The apparent degradation of the germanium material begins to degrade at about 100 ° C between 200 ° C and 300 ° C, which may lead to catastrophic failure of the fiber. Due to the high reflectivity of the substrate surface, germanium components are AR coating.
