Our spherical plano-concave germanium lenses are primarily accustomed to diverge a beam from a collimated gentle source, or to improve the focal length of the optical technique.
Just about anything in excess of one hundredºC just isn't encouraged. By the point it reaches two hundredºC it is almost opaque in the least wavelengths. If you want a substantial temperature window, you’re greater suited to stay with a material like MgF2, YAG or our old friend sapphire.
Novotech has the capacity to execute diamond turning, sprucing, and custom made producing for all orders from prototype to generation quantities.
You unquestionably don’t would like to breathe in germanium dust so treatment needs to be taken although dealing with these optics. Employing gloves When attainable and washing hands really should be part of any typical working treatment.

It is the Exclusive hardness of germanium that gives it its exclusive ruggedness; Ge features a Knoop hardness of 780. It is just a high density content, at five.33 g/cm3, and allowances needs to be created for this body weight If you're planning a website pounds delicate system.
When not in use, we recommend storing your germanium Home windows wrapped in lens tissue with humidity down below thirty% and involving fifteen and 25ºC. Although germanium is rather challenging stuff, these are generally The perfect situations that can prolong the life of your window.
We provide precision cylinder lenses in spherical, rectangular or quadratic shapes to satisfy your requirements. The optical elements are offered with large-reflection or antireflection coatings with the DUV, UV, VIS and IR spectral ranges. The Particular coating improves the cylinder lenses and makes them far more resistant. Data Sheet
It may be Slice, polished and formed into lenses and Home windows Employed in infrared detector products along with infrared spectroscopes.
Germanium isn't mined as being a Key steel but is produced for a by-products of zinc manufacturing along with from coal fly ash.
Jenoptik´s OrthoLine optical alignment cubes are designed largely for processes that involve precision datum registration - such as applications inside the lifestyle and well being sciences, metrology and defense.
Rather than needing multiple different cameras to accomplish most of these duties, It can save you lots of money with “intelligent” add-on lenses which might be applied amid multiple suitable cameras without having special recalibration for each digicam and be capable of quickly swap out lenses on The task.
Optical windows : key usage of germanium with Excellent transmission in the IR and no transmission while in the obvious. Usually, germanium Home windows are strengthened with DLC coating on one experience.
