Infrared Germanium Lens
Germanium has a wide spectral working range (2-16µm) and impermeability in the visible spectral range. Germanium is very suitable for infrared laser applications. It is not easy to react with air, water, alkali metals and acids (except for nitric acid).
Product Code:GA-IRGe
Application of Infrared Germanium Lens
Germanium lenses are mainly used in infrared thermometers, infrared thermal imagers, CO2 lasers and other equipment.
GiAi Advantage
The germanium lens produced by GiAi uses optical-grade single crystal germanium as the substrate and is processed by a new type of polishing technology. The surface has a very high surface accuracy. The two surfaces of the germanium lens will be coated with 8-12μm antireflection coating, which is extremely The reflectance of the substrate is greatly reduced, and the transmittance of the antireflection coating in the working band reaches more than 95%.
