Our germanium lenses have a large refractive index—the very best refractive index between available IR transmitters. In addition it displays negligible chromatic aberration as a consequence of small dispersion.
Huge-angle lenses are great for dwelling inspectors that ought to scan the outside of a dwelling when you’ll be capable of see the largest place directly.
Deliver us your distinct demands, and our technical income representatives will analyze what is needed to provide All set-to-use parts in just your guide time.
You surely don’t would like to breathe in germanium dust so care has to be taken while handling these optics. Utilizing gloves Each time doable and washing arms should be A part of any common running method.
Our metallic or dielectric coatings on mirrors are optimized to meet your specifications. Concurrently, these coatings defend the parts against environmental impact and increase the reflection. Jenoptik assessments all elements in accordance with DIN ISO or MIL requirements.
In fact, at a watch-popping Knoop Hardness of 2000kg/mm2, one particular may well wonder, why wouldn’t I just use sapphire Home more info windows as opposed to germanium? Whilst sapphire is the undisputed champion of strong optics while in the UV/VIS and mid-IR having a wavelength vary that dips to the far UV array at 150nm, it may only be utilised around 4.
Most often the coating used is diamond-like carbon (DLC) which has a refractive index of 2.0. DLC is extremely difficult, which implies that windows coated with it can be used in ruggedised merchandise which can be issue to harsh environmental situations.

1 quite common situation we see germanium utilized is within large and reduced velocity wind tunnels for jet propulsion reports. Usually, these Home windows are much larger than inventory configurations achieving measurements in excess of one hundred ninety-200mm.
Ge lenses can transmit infrared wavelengths with no major reduction, letting for apparent and exact imaging.

Recognizing the distinction between the various lens varieties might help determine which one to employ when so that you can get most troubleshooting facts.
Raw germanium have a comparatively typical transmission from the IR (lower than 50%) but Anti-replicate or DLC remedies do strengthen a great deal it’s transmittance.
