Our germanium lenses Have got a large refractive index—the best refractive index amongst readily available IR transmitters. It also exhibits small chromatic aberration due to minimal dispersion.
Unfortunately Germanium is sensible to superior temperature with degradation of its optical Houses about one hundred°C.
Please bear in mind this could closely decrease the performance and visual appeal of our web site. Adjustments will get result after you reload the page.

Lattice Materials is usually a environment leader in production remarkably intricate germanium optics in prototype or production portions.
One typical software for germanium is in night time vision goggles. For these kinds of apps, each The within and outdoors surfaces of your germanium is polished to some mirror finish and coated with multi-layered slim movie filters to reduce any reflection of IR light-weight.
Click on the several classification headings to learn far more. You may as well transform a few of your Choices. Take note that blocking some varieties of cookies may possibly impression your expertise on our websites plus the companies we have the ability to provide.
We provide precision cylinder lenses in round, rectangular or quadratic shapes to satisfy your prerequisites. The optical elements can be obtained with large-reflection or antireflection coatings for the DUV, UV, VIS and IR spectral ranges. The Specific coating improves the cylinder lenses and makes them much more resistant. Info Sheet
By growing an individual crystal, we generate elements using a steady crystal construction and large purity.
Germanium has a significant refractive index, so lenses fabricated from Ge can concentrate gentle a lot more competently and provide better-resolution imaging like thermal cameras, remote sensing, and night time eyesight gadgets.

Even though you're going to get a greater, far more controlled cleaning and can be utilized for stubborn stains, care have to be taken to operate in a controlled moisture-cost-free ecosystem and we don't propose this for typical finish-consumers.
These are rookie quantities and in many apps we’ll want to spice up our window alerts through various coatings. When This can be a downside for optical Home windows this property is available in handy for novel lens layouts and ATR optics in which refraction is wished-for.
