Optics from Germanium

Due to the transparency in the infrared region of the spectrum, metallic germanium is of strategic importance in the production of optical elements of infrared optics.

Certificated

Germanium has valuable optical characteristics — the ability to pass infrared rays.

Optical parts from Germanium have found wide application in night vision devices, passive thermal imaging systems, computer technology, firefighting systems, aviation technology, Earth exploration from satellites. In addition to that, Germanium is used in optical devices for infrared spectroscopy and infrared detectors. Optics from Germanium are used in CO2 lasers (gas).

Technical specifications

The refractive index 4.1 ÷ 4.0, depending on the wavelength of the radiation
The transmission in the IR spectral range, nm 3000 to 5000, 8000 to 12000
