Our germanium lenses Have got a substantial refractive index—the highest refractive index among the readily available IR transmitters. It also reveals minimum chromatic aberration due to lower dispersion.
Germanium famously generally known as predicted by Mendeleev prior to its true discovery ultimately nineteenth century, is extensively Utilized in optics to be a element content for IR apps. It's got also attention-grabbing semi-conductor Qualities that we will not talk about into specifics On this tutorial.

Thorough managing and cleaning: Germanium optics are very tricky and brittle. Appropriate cleaning and packaging techniques lower any damage or contamination that might influence its optical general performance.
Avantier Inc. is definitely an unparalleled chief in providing imaging techniques methods and optical remedies.
Grinding and sharpening: The Original shaping of the germanium substrate making use of precision grinding and sharpening is significant for a smooth and uniform surface area. A series optical germanium lens of steps are followed, Every with significantly finer abrasives, until we achieve the specified surface complete.
Specialized measurement and inspection: Working with specialized measurement equipment and inspection machines, we make certain that the floor roughness, curvature, and various significant parameters satisfy rigorous tolerances and high quality expectations.
Firebird Optics manufactures these sorts of Home windows in many geometries, coatings and may produce lenses, prisms and different other optical parts from germanium. Now back again for your regularly scheduled programming…
These significant-top quality cylinder optics are ideal for use in laser scanning, laser projection, beam homogenization and PCB fabrication. They are also an excellent Remedy in fault Investigation.
Coatings from Jenoptik let you guidebook beams inside of a focused way. They filter certain wavelengths, mirror optics or redirect them and lessen reflection if needed. We provide the next:
An uncoated germanium window is an honest IR generalist but precise optical coatings can definitely kick matters up a notch.
Germanium (Ge) is usually a shiny, difficult ingredient with a Knoop Hardness of 780kg/mm2 which makes it, in conjunction with its significantly stronger sister sapphire, the default prospect for apps in which the atmosphere is probably going to put a beating on the fabric.
