Our spherical plano-concave germanium lenses are generally utilized to diverge a beam from the collimated gentle supply, or to raise the focal size of the optical procedure.
It's also truly worth noting that germanium is fairly extra brittle that silicon and for that reason should be tackle with care throughout machining.
Ahead your product demands and We are going to react that has a estimate. For every other inquiries or concerns please Get hold of our well-informed profits personnel.

They can also be Utilized in focusing applications, and also have prevalent use in several fields, from science to field to defense. We advise these lenses be oriented so that the flat aspect faces the specified focal airplane.
A single typical application for germanium is in night time vision goggles. For these types of purposes, the two The within and outside surfaces on the germanium is polished to a mirror end and coated with multi-layered thin movie filters to lower any reflection of IR light.
Germanium’s transparency while in the infrared wavelengths ensure it is a vital and commonly made use of content in infrared optics.
Specialized measurement and inspection: Applying specialised measurement instruments and inspection devices, we make sure the floor roughness, curvature, together with other important parameters meet up with rigorous tolerances and excellent criteria.
1 very common state of affairs we see germanium used is inside substantial and small pace wind tunnels for jet propulsion studies. Commonly, these windows are much larger than stock configurations achieving measurements in excess of one hundred ninety-200mm.
Do you've got a tailor made requirement for germanium optical elements? Send out us your specific needs, and our complex read more sales representatives will evaluate what is required to deliver All set-to-use parts in just your guide time.
Sprucing & coating: Our sprucing procedures deliver Outstanding levels of flatness, surface roughness, and surface top quality. Germanium lenses often demand optical or anti-reflection coatings to enhance their effectiveness and toughness.
Alternatively, You can utilize liquid CO2 from a specialised nozzle for cleansing while this involves more Price tag in phrases of apparatus.
Germanium (Ge) can be a shiny, tough ingredient by using a Knoop Hardness of 780kg/mm2 making it, coupled with its much much better sister sapphire, the default candidate for apps exactly where the ecosystem is likely to put a beating on the fabric.
