Our germanium lenses Possess a high refractive index—the best refractive index between available IR transmitters. Additionally, it reveals small chromatic aberration due to very low dispersion.
Just about anything around a hundredºC is not really suggested. By the time it reaches two hundredºC it is sort of opaque in the least wavelengths. If you want a high temperature window, you’re much better suited to follow a cloth like MgF2, YAG or our old Buddy sapphire.
The obvious way to clean up the Home windows is to work with either ethanol, isopropyl alcohol, methanol, reagent-grade acetone or lint-no cost lens cloths. It's also possible to use nitric acid but this material, while alright for germanium can corrode other optics or mounts that may be nearby as part of your program.
In case you’re scanning a large spot that’s further absent, like the ceiling or roof of the factory or warehouse, you’ll have to have a telephoto lens (2x or 4x is often features enough zoom) to have the ability to begin to see the detail you may need from additional away.

Shanghai Optics manufactures high quality germanium lenses in An array of well known sizes, from 5m m to 350 mm in diameter.
Novotech is a worldwide supplier of evaporation quality Germanium. We help IR coating organizations along with the fiber optics business with their materials wants.
This will make Ge ideal for use in programs where by lenses are subjected to extreme environmental disorders or involve efficient warmth dissipation, including infrared cameras Employed in aerospace or navy applications.
Firebird Optics manufactures these types of windows in different geometries, coatings and may also make lenses, prisms and different other optical components from germanium. Now back again to your on a regular basis scheduled programming…
Germanium features a higher refractive index, so lenses manufactured from Ge can focus light extra competently and deliver better-resolution imaging like thermal cameras, distant sensing, and night vision equipment.
Developing a solitary crystal of germanium would be the starting point for manufacturing high-high quality elements. The crystal composition and defect density can significantly influence its optical and electrical Homes.
Now for some pleasurable things. We hear from an abundance of our buyers where their germanium windows are here observing motion. Here are a few highlights:
Incorporating an aspheric lens into an optical assembly has the opportunity to greatly simplify the method, and perhaps the addition of fairly large germanium lens might truly minimize the methods excess weight.
