Product Description
General Introduction:
In the range of 2-12μm, germanium is the most commonly used material for fabrication of optical lenses and optical Windows in efficient infrared imaging systems. Germanium is characterized by a high refractive index (about 4.0 in the 2-14μm band), minimal surface curvature, and small chromatic aberration, and is usually not required to be corrected in low-power imaging systems.
Main Applying:
1).Infrared thermometers
2).Infrared thermal imagers
3).CO2 Lasers; Multi-laser systems
Main Highlights:
The wide spectral range of germanium (2-16um) Germanium is very suitable for infrared laser applications because of its high transmittance in the visible spectrum.It also does not react easily with air, water, alkali metals and acids (except nitric acid)
Main Technical Data:
The listed prices are only for reference. The final price is up to the substrate type, substrate grade, product size, suface finish, surface quality and Physical & Optical request standards.
