A Review Of optical germanium lenses

Plano-convex Ge lenses are flat on 1 facet and convex on the other. These lenses have a beneficial focal length, and in many cases are used for gentle collimation.

No water solubility- advantage in excess of salty Home windows which include KBr and NaCl that are exceptionally hygroscopic.

Another thought is germanium’s density. At 5.33g/cm3 it does not float just like a butterfly and sting similar to a bee. It’s heavy. Quite heavy and this may have to be regarded as when developing bodyweight-sensitive methods.

One widespread software for germanium is in night time vision goggles. For most of these purposes, both The within and outside surfaces with the germanium is polished to a mirror end and coated with multi-layered slender film filters to scale back any reflection of IR light.
