Other than certain specialised makes use of in electronics, germanium these days is used mostly in the optics industry because its Attributes help it become ideal for optical devices including lasers, aim lenses for microscopes and also other scientific instrumentation and broad-angle photographic lenses.
Our germanium lenses Possess a substantial refractive index—the highest refractive index between available IR transmitters. Additionally, it reveals small chromatic aberration resulting from small dispersion.
We are able to manufacture aspheres in rotationally symmetrical, ellipsoid and off-axis styles to fulfill your certain needs. In this process, we are on the list of handful of companies globally to implement various optical elements, like glass, glass ceramics, quartz glass, crystals for example calcium fluoride, magnesium fluoride, germanium and silicon and metals. The antireflection coatings around the aspherical parts deal with a spectral vary from DUV to IR.
Ship us your precise requirements, and our complex gross sales representatives will examine what is necessary to provide Completely ready-to-use factors inside your lead time.
In case you’re scanning a large area that’s even more absent, much like the ceiling or roof of the factory or warehouse, you’ll have to have a telephoto lens (2x or 4x is normally presents sufficient zoom) to have the ability to begin to see the detail you may need from further more away.
We provide plane, spherical, aspherical, cylindrical and toric mirrors for a wide range of purposes. They're developed and manufactured by Jenoptik to satisfy your certain necessities. Also to standard substrate resources, we also use metallic substrates.

Germanium lenses are optical lenses made from polished germanium. Germanium Optics are rugged and resistant to corrosion, and are perfect for severe environments and purposes exactly where There is certainly frequent publicity to The weather.
This will make Ge ideal for use in purposes where by lenses are subjected to Excessive environmental conditions or demand effective warmth dissipation, for instance infrared cameras Utilized in aerospace or armed forces applications.

Germanium features a significant refractive index, so lenses made from Ge can concentration light a lot more competently and deliver higher-resolution imaging which include thermal cameras, remote sensing, and evening eyesight gadgets.
Jenoptik´s OrthoLine optical alignment cubes are created principally for processes that need precision datum registration - which includes purposes during the lifetime and wellbeing sciences, metrology and protection.
In lieu of needing numerous diverse cameras to accomplish all of these responsibilities, you can save a lot of cash with “good” add-on lenses that could be made use of amongst a number of appropriate cameras without Particular recalibration for every digicam and be able to rapidly swap out lenses on The task.
Germanium was initial uncovered by a German chemist identified as Clemens Winkler (1838–1904) in 1886. Winkler labored at what is now the Freiberg University of Mining and Engineering, and was requested by a colleague to analyse an abnormal new mineral which had been present in a nearby mine.
