Feature of germanium window
Ge Windows Germanium (Ge) is the preferred lens and window material for high performance infrared imaging systems in the 8–12 μm wavelength band. Its high refractive index makes Ge ideal for low power imaging systems because of minimum surface curvature. Chromatic aberration is small, often eliminating the need for correction. Germanium is most widely used for lenses and windows in IR systems operating in the 2 μm - 12 μm range. Its transmission is very temperature sensitive, becoming opaque near 100°C. Environment does not cause problems because Germanium is inert, mechanically rugged, and fairly hard.
It is also used extensively as a substrate for production of optical filters. Germanium covers the whole of the 8-14 micron
thermal band and is used in lens systems for thermal imaging. It can be AR coated with diamond producing an extremely tough front
optic. Application as window, lens, beam splitter, ATR prism or filter in spectrometers and in thermal imaging.Germanium is a high index material that is used to manufacture Attenuated Total reflection (ATR) prisms for spectroscopy. Its
refractive index is such that germanium makes an effective natural 50% beam splitter without the need for coatings.
