Unique purposes for germanium Home windows involve military and defence devices like night vision goggles and warmth location detection devices employed by hearth-combating solutions.
Our germanium lenses Possess a significant refractive index—the highest refractive index amid available IR transmitters. Furthermore, it displays negligible chromatic aberration as a result of low dispersion.
Germanium can also be matter to thermal runaway. What This suggests would be that the transmission will reduce as temperature boosts, plus the lens turns into opaque. Due to this thermal runaway result, germanium lenses should really only be used at temperatures below 100°C.
Germanium has superb thermal stability. It may stand up to substantial running temperatures with no degrading optical general performance.

Lattice Elements is really a planet leader in producing really intricate germanium optics in prototype or output portions.
It's the Exclusive hardness of germanium that offers it its special ruggedness; Ge contains a Knoop hardness of 780. It's a substantial density product, at 5.33 g/cm3, and allowances has to be manufactured for this pounds Should you be coming up with a pounds delicate system.
Click on the various group headings to see far more. You may as well adjust some of your Choices. Notice that blocking some sorts of cookies may possibly effect your expertise on our Internet sites along with the companies we will be able to provide.
This would make Ge ideal for use in purposes the place lenses are subjected to Serious environmental disorders or have to have economical warmth dissipation, which include infrared cameras Employed in aerospace or military services applications.
Infrared Filters, Windows and canopy Glass for Hermetic Solder Sealing We acquire and manufacture various optical filters. They can be used to Enhance the effectiveness of radiation detectors and impact the sign-to-sound ratio or reaction sensitivity of your detector. The coatings are suitable for workpieces made out of these types of materials as germanium, silicon and sapphire.
We could make customized specs to non-normal sizes of optical crystals. Novotech can supply the fabric fabricated to most shopper’s technical specs. With an in depth fabrication potential, we will generate regular generated lens blanks inside of a just one-to two-week time period.
