At significant temperature optical grade germanium is matter to excessive absorption resulting from elevated number of thermally generated holes. As it could be found from spectra absorption expansion gets important at temperatures more than about forty five°C.
Our germanium lenses Have got a substantial refractive index—the highest refractive index among the readily available IR transmitters. In addition it displays minimal chromatic aberration on account of low dispersion.
Everything above one hundredºC is just not advisable. By the point it reaches 200ºC it is sort of opaque in any way wavelengths. If you need a high temperature window, you’re superior suited to stick to a fabric like MgF2, YAG or our previous Mate sapphire.
Ahead your content specifications and we will respond that has a estimate. For every other inquiries or issues be sure to Get hold of our proficient sales employees.

We provide plane, spherical, aspherical, cylindrical and toric mirrors for a variety of applications. They're built and created by Jenoptik to meet your unique prerequisites. In addition to standard substrate materials, we also use metallic substrates.
We’ve by now explored why you would pick germanium above sapphire but why would you decide germanium in excess of silicon or vice versa?
Avantier Inc. is really an unparalleled leader in delivering imaging units remedies and optical alternatives.
Thermal digital camera lenses are made of Germanium as a result of product’s special Attributes with regard to the Infrared spectrum. Germanium is a component you can find inside the periodic desk and directly from character.
Firebird Optics manufactures a lot of these windows in different geometries, coatings and also can develop lenses, prisms and various other optical elements from germanium. Now back again to the consistently scheduled check here programming…
Germanium winds up in a few intriguing destinations which include protection plane navigation, reconnaissance and surveillance techniques soaring within the stratosphere on an airplane or even as Section of a satellite.
Coatings from Jenoptik help you tutorial beams in the specific method. They filter specific wavelengths, mirror optics or redirect them and reduce reflection if expected. We provide the next:
Alternatively, You should utilize liquid CO2 from the specialised nozzle for cleansing although this involves added Price tag in phrases of equipment.
Germanium was first employed on a substantial scale to replace The most primary electronic components, the diode.
