Lattice Materials is exceptionally Geared up to produce optical factors, and germanium lenses particularly, to specific optical specs with any ending you require.
For a full breakdown of tips on how to wade through most of the significant optical window decisions Examine our optical window guideline.
Germanium is usually subject matter to thermal runaway. What This implies would be that the transmission will reduce as temperature increases, plus the lens gets opaque. Because of this thermal runaway influence, germanium lenses must only be made use of at temperatures under a hundred°C.
Ahead your material demands and We are going to reply which has a quote. For every other inquiries or queries make sure you Make contact with our experienced revenue workers.
No water solubility- edge more than salty Home windows like KBr and NaCl which have been really hygroscopic.
You may electronic mail the website proprietor to let them know you ended up blocked. Be sure to consist of That which you were being performing when this webpage came up plus the Cloudflare Ray ID uncovered at The underside of the page.
These cookies optical germanium lenses are strictly necessary to supply you with expert services offered via our Web-site and also to use some of its capabilities.
The end goal is to generate germanium optics that meet up with or exceed the demanding demands of various purposes, from infrared thermal imaging and sensing to spectroscopy and laser devices.
We produce and manufacture optical factors in the highest top quality that you can use in many various fields of software, from laser materials processing to biotechnology, professional medical technological innovation, protection and protection as well as semiconductor market.
These are exceptionally robust, guarded in opposition to environmental impression and price-helpful. The filters also meet up with all the requirements in the DIN ISO or MIL expectations and comprise no radioactive substances. If required, we can offer all filters with edges which have been well suited for soldering, so that they're straightforward to combine into your present units.
Most of the raw materials originates from China, Russia and United states currently being also significant suppliers, high-quality product is available all over the place.
The sharp transmission Reduce-off right before 2µm also permits germanium for use as a protracted go filter, only transmitting wavelengths in extra of twoµm and totally blocking everything ahead of it.
An uncoated germanium window is an honest IR generalist but unique optical coatings can definitely kick factors up a notch.
Uncooked germanium materials is very really hard but can continue to properly be machined and polished into optical parts:
