Plano-convex Ge lenses are flat on a single aspect and convex on the opposite. These lenses Possess a beneficial focal length, and are sometimes utilized for light collimation.
Ge can be interesting for its very low optical dispersion and thus pretty lower chromatic dispersion in it’s transmission spectrum.
Everything above 100ºC is not suggested. By the time it reaches two hundredºC it is sort of opaque at all wavelengths. If you need a substantial temperature window, you’re far better suited to stick to a cloth like MgF2, YAG or our previous Pal sapphire.

Germanium finally ends up in certain fascinating sites including protection plane navigation, reconnaissance and surveillance devices soaring from the stratosphere on an plane or whilst A part of a satellite.
Germanium and germanium oxide have an incredibly large refractive index, meaning that for a few window applications anti-reflective coating is needed.
At Lattice Materials, we personalized manufacture germanium lenses with a very well-described and controlled method to make sure that they fulfill stringent effectiveness specifications:
Germanium (Ge) is really a shiny, really hard component that has a Knoop Hardness of 780kg/mm2 making it, coupled with its much more robust sister sapphire, the default candidate for apps where by the surroundings is probably going To place a beating on the fabric.
