Aside from sure specialised employs in electronics, germanium these days is made use of largely from the optics industry due to the fact its Attributes ensure it is ideal for optical devices like lasers, aim lenses for microscopes as well as other scientific instrumentation and huge-angle photographic lenses.
Our germanium lenses Have a very significant refractive index—the highest refractive index among available IR transmitters. Furthermore, it displays negligible chromatic aberration as a result of small dispersion.
Sad to say Germanium is sensible to high temperature with degradation of its optical Qualities about one hundred°C.
Fabrication: Our specially developed handling and machining methods help to eliminate sub-area injury and chipping. We maintain quite a few prime-high quality multi-axis CNC vertical mills devoted to machining elaborate lenses in both production or prototype quantities.

When not in use, we endorse storing your germanium windows wrapped in lens tissue with humidity underneath thirty% and among 15 and twenty fiveºC. Whilst germanium is very difficult stuff, these are the ideal ailments which will extend the daily life of your respective window.
Thermal digital camera lenses are made of Germanium as a result of materials’s distinctive Houses with respect into the Infrared spectrum. Germanium is an element you can find from the periodic table and straight from mother nature.
By expanding only one crystal, we generate parts with a regular crystal composition and large purity.
These significant-high quality cylinder optics are perfect for use in laser scanning, laser projection, beam homogenization and PCB fabrication. Also they are a great Option in fault analysis.
Due to the compact design, you would like fewer elements and products for diffractive optics than for regular methods. What is much more, assembly is simpler. This would make optical structures for broadband purposes much more Expense-effective to put into action.
Now for some exciting stuff. We listen to from a good amount of our consumers where their germanium windows are seeing motion. Here are a few highlights:
Germanium (Ge) is often a shiny, difficult factor with a Knoop Hardness of 780kg/mm2 making it, in conjunction with more info its far more powerful sister sapphire, the default applicant for apps where by the atmosphere is likely to put a beating on the material.
