The best Side of optical germanium lens

They are also normally used in aerospace industries one example is in satellite imagery sensors and in everyday life and health care sciences for health care diagnostics.

Our germanium lenses Possess a high refractive index—the very best refractive index amid available IR transmitters. Furthermore, it displays minimum chromatic aberration as a result of minimal dispersion.

Germanium can be matter to thermal runaway. What This suggests is that the transmission will minimize as temperature boosts, along with the lens will become opaque. Due to this thermal runaway influence, germanium lenses need to only be made use of at temperatures beneath one hundred°C.
