Our germanium lenses have a significant refractive index—the highest refractive index amongst available IR transmitters. Furthermore, it exhibits minimal chromatic aberration as a result of lower dispersion.
Count on our proficient crystal advancement technicians to overcome these problems and deliver demanding specifications.
Germanium has superb thermal stability. It could possibly stand up to substantial working temperatures with no degrading optical effectiveness.

Wafers : as being a semi conductor product, like Silicon, it is actually widely used as a thin substrate for Digital component.
Just one popular software for germanium is in night vision goggles. For a lot of these purposes, both of those the inside and out of doors surfaces on the germanium is polished into a mirror complete and coated with multi-layered slender movie filters to lessen any reflection of IR mild.
The top objective is to supply germanium optics that meet up with or exceed the demanding prerequisites of various applications, from infrared thermal imaging and sensing to spectroscopy and laser methods.
Comparable to how seen light digicam lenses are a strong glass shape, thermal digital camera lenses are reliable Germanium. Just as glass is clear to visible gentle, Germanium is transparent on the wavelength band of infrared radiation, which most thermal cameras use.
Firebird Optics manufactures these sorts of windows in several geometries, coatings and also can produce lenses, prisms and a variety of other optical components from germanium. Now back again on your routinely scheduled programming…
At Shanghai Optics we manufacture lots of germanium lenses with many anti reflection coatings. Spherical plano-concave, p-convex, concave-convex and aspheric lenses are all out there in a wide variety of measurements. We may also be ready to accommodate Distinctive orders in case you have to have a dimension, shape or AR coating.

As an alternative to needing several diverse cameras to finish every one of these responsibilities, you can save a lot of cash with “smart” incorporate-on lenses that can be utilized among the a number of suitable cameras without the need of special recalibration for every digicam and have the ability to rapidly swap out lenses on The work.
Following, the crystal is processed into the click here desired shape employing precision cutting, grinding, and machining techniques to achieve the precise flatness or curvature essential.
