At high temperature optical quality germanium is subject to excessive absorption as a result of improved variety of thermally generated holes. As it could be found from spectra absorption expansion gets to be important at temperatures in excess of about 45°C.

Our germanium lenses Have a very large refractive index—the highest refractive index between readily available IR transmitters. What's more, it reveals nominal chromatic aberration on account of reduced dispersion.

Germanium is usually topic to thermal runaway. What this means would be that the transmission will minimize as temperature increases, plus the lens results in being opaque. Because of this thermal runaway result, germanium lenses should only be employed at temperatures under a hundred°C.

Send us your unique demands, and our technical sales Reps will analyze what is needed to provide Prepared-to-use factors inside your guide time.

Jenoptik manufactures hybrid components in optical substance for infrared programs.

Germanium was very first discovered by a German chemist known as Clemens Winkler (1838–1904) in 1886. Winkler labored at what's now the Freiberg College of Mining and Technological know-how, and was questioned by a colleague to analyse an abnormal new mineral which had been located in a close-by mine.
