Besides certain specialised employs in electronics, germanium currently is employed mostly in the optics marketplace simply because its properties ensure it is perfect for optical devices for instance lasers, objective lenses for microscopes and various scientific instrumentation and vast-angle photographic lenses.
Our germanium lenses Have got a large refractive index—the very best refractive index among the available IR transmitters. In addition it exhibits small chromatic aberration resulting from lower dispersion.
Germanium famously referred to as predicted by Mendeleev right before its actual discovery ultimately nineteenth century, is extensively Utilized in optics as a element product for IR programs. It's got also exciting semi-conductor Houses that we are going to not go over into information During this guide.
Germanium has exceptional thermal stability. It can withstand large functioning temperatures with out degrading optical general performance.
To find out more about Germanium Home windows from UQG Optics, or any of our optical Home windows get in touch with us on 01223 420329 or e mail our sales team at [email protected]

Germanium is likewise utilised thoroughly as being a substrate for production of optical filters. Germanium addresses The entire in the 8-fourteen micron thermal band and is also Utilized in lens systems for thermal imaging. Germanium is usually AR coated with Diamond developing an incredibly tough front optic.

Aspherical germanium lenses : intended and useful for Increased optical Qualities and for applications that need pounds conserving. Germanium can be diamond was substantial surface top quality aspheres.
Do there is a custom prerequisite for germanium optical factors? Send out us your particular necessities, and our technical income Associates will assess what is necessary to deliver All set-to-use factors within your direct time.
Both germanium and germanium oxide are transparent to infrared radiation and so are commonly used in the manufacture of spherical lenses and windows for prime performance infrared spectroscopes and thermal imaging units.
I consent that JENOPTIK AG or even the Jenoptik Team company liable for my request may approach my e-mail deal with and my other personal data entered from the Speak to variety in an effort to Get hold of me by e-mail, phone or usually and ship me information on services supplied by the Jenoptik Team.
Uncooked germanium have a relatively normal transmission while in the IR (fewer than 50%) but Anti-replicate or DLC treatment options do enhance a whole lot it’s transmittance.
