Our spherical plano-concave germanium lenses are mainly used to diverge a beam from the collimated gentle supply, or to boost the focal length of the optical process.
Just about anything above one hundredºC is not advisable. By the point it reaches 200ºC it is almost opaque in the slightest degree wavelengths. If you need a superior temperature window, you’re superior suited to stay with a cloth like MgF2, YAG or our previous Close friend sapphire.
The easiest way to clear the Home windows is to implement either ethanol, isopropyl Alcoholic beverages, methanol, reagent-grade acetone or lint-free lens cloths. It's also possible to use nitric acid but this content, while ok for germanium can corrode other optics or mounts that may be close by inside your procedure.
To see more details on Germanium Home windows from UQG Optics, or any of our optical Home windows call us on 01223 420329 or e-mail our income staff at facts@uqgoptics.com

The truth is, at an eye fixed-popping Knoop Hardness of 2000kg/mm2, just one could marvel, why wouldn’t I just use sapphire Home windows in lieu of germanium? Though sapphire is the undisputed winner of sturdy optics inside the UV/VIS and mid-IR having a wavelength variety that dips into the considerably UV selection at 150nm, it could possibly only be applied as many as 4.
Germanium’s transparency while in the infrared wavelengths help it become a vital and greatly made use of material in infrared optics.
Specialised measurement and inspection: Working with specialized measurement tools and inspection equipment, we make sure the floor roughness, curvature, along with other crucial parameters fulfill rigid tolerances and high quality benchmarks.

A lot of the raw materials originates from China, Russia and USA becoming also crucial suppliers, top quality content is offered in all places.
Making a one crystal of germanium may be the place to begin for manufacturing large-high quality elements. The crystal construction and defect density can drastically have an effect on its optical and electrical Homes.
Now for some enjoyable stuff. We hear from lots of our consumers the place their germanium windows are viewing action. Below are a few highlights:
Germanium (Ge) is really a shiny, challenging aspect using a Knoop Hardness of 780kg/mm2 making it, coupled with its significantly much better sister sapphire, the default applicant for apps where by the atmosphere is likely to put a beating on the material.
