Our germanium lenses Possess a higher refractive index—the best refractive index between readily available IR transmitters. In addition, it displays small chromatic aberration on account of minimal dispersion.
Our output team takes advantage of precision CNC curve turbines to supply very best-in-course germanium lenses for any of your respective specifications — from prototype requests through comprehensive creation volumes.
The obvious way to clean up the windows is to utilize both ethanol, isopropyl Liquor, methanol, reagent-quality acetone or lint-no cost lens cloths. You may also use nitric acid but this content, when all right for germanium can corrode other optics or mounts Which might be close by in your method.

Wafers : as being a semi conductor material, like Silicon, it can be extensively used as a skinny substrate for electronic part.
It's the Specific hardness of germanium that gives it its exceptional ruggedness; Ge incorporates a Knoop hardness of 780. It's a superior density content, at five.33 g/cm3, and allowances have to be made for this body weight In case you are designing a fat sensitive process.
Grinding and polishing: The initial shaping on the germanium substrate applying precision grinding and sprucing is vital for any clean and uniform floor. A series of methods are followed, Every with significantly finer abrasives, until finally we achieve the desired area end.
Thermal camera lenses are created of Germanium because of the materials’s special Qualities with respect into the Infrared spectrum. Germanium is a component you'll find within the periodic desk and straight from character.
Firebird Optics manufactures a lot of these windows in different geometries, coatings and might also produce lenses, prisms and numerous other optical elements from germanium. Now back again to the consistently scheduled programming…
It has superior transmission while in the eight to 14 µm variety masking the thermal Infrared light, thus it's a fabric of option for thermal and evening eyesight. What's more, it displays a higher refractive index which help substantial open aperture angle optical part’s design and style.
This higher-density window contains a thermal website escape which makes the transmission cut down since the temperature from the window boosts.
Content Selection: Substantial-high-quality germanium substrate is essential for manufacturing high-efficiency lenses, as any defects or impurities from the germanium crystals could impact the optical Qualities in the completed lens. Trust in Lattice to deliver high-quality custom-grown germanium to make sure large-top quality lenses.
Optical windows : principal usage of germanium with very good transmission in the IR and no transmission during the obvious. Generally, germanium windows are strengthened with DLC coating on a single encounter.
