Custom-made Ceramic
and Glass Components

Germanium

Germanium is a useful material for thermal imaging due to high transmission levels between 8 – 14 microns, so it is often formed into optics such as lenses and windows. The material is typically used in infrared laser applications and has a high index of refraction, meaning that anti-reflection coatings are frequently used to improve performance. Diamond coating also ensures that optics are reasonably tough. Germanium is stable in air and water and is unaffected by alkalis and acids, with the exception of nitric acid.

Characteristics of germanium include:

  • High density (approx. 5.33g/cm3)
  • Good transmission levels in the infrared
  • Chemically stable
  • High index of refraction
