It's the Particular check here hardness of germanium that provides it its unique ruggedness; Ge features a Knoop hardness of 780. It is just a superior density material, at 5.33 g/cm3, and allowances have to be designed for this pounds When you are developing a pounds delicate method.

Avantier Inc. is surely an unparalleled leader in providing imaging units methods and optical remedies.

This can make Ge ideal for use in purposes wherever lenses are subjected to Excessive environmental situations or require economical heat dissipation, like infrared cameras Employed in aerospace or armed forces applications.

Curiously, resulting from its similar crystal structure to Diamond could be coated that has a DLC layer (Diamond Like Carbon) which in addition to reducing the reflection on it’s surface, provides a diamond strong protective layer. Lastly Germanium just isn't transparent inside the noticeable which can be beneficial to target IR mild.

Below you can find list of primary properties of Germanium together with its transmission and absorption spectra.

Both equally germanium and germanium oxide are transparent to infrared radiation and so are commonly Employed in the manufacture of spherical lenses and windows for top effectiveness infrared spectroscopes and thermal imaging techniques.

Now for some pleasurable stuff. We hear from a lot of our consumers the place their germanium windows are looking at motion. Below are a few highlights:

Raw germanium substance is quite challenging but can still properly be machined and polished into optical parts:
