Our germanium lenses Have a very higher refractive index—the best refractive index amid readily available IR transmitters. In addition, it exhibits minimum chromatic aberration because of very low dispersion.
Regrettably Germanium is reasonable to large temperature with degradation of its optical Qualities about 100°C.
Part of The key reason why for this is larger driven lasers cause temperature increases, dramatically dropping transmission Houses more than a hundredºC and inevitably detrimental the substrate by itself the moment temperatures in close proximity to 600ºC are achieved.

Both of those monocrystalline and polycrystalline Ge may be used for manufacturing of optical parts. We develop Germanium lenses and windows for infrared thermal imaging apps and pyrometry (see our webpage Germanium Home windows and lenses for thermography).
The tip intention is to supply germanium optics that meet up with or exceed the demanding needs of varied applications, from infrared thermal imaging and sensing to spectroscopy and laser techniques.
Specialised measurement read more and inspection: Applying specialised measurement tools and inspection gear, we be sure that the area roughness, curvature, and various crucial parameters satisfy stringent tolerances and good quality criteria.

It has fantastic transmission inside the eight to fourteen µm variety covering the thermal Infrared gentle, consequently it is actually a material of option for thermal and night vision. In addition it displays a high refractive index which permit superior open aperture angle optical part’s design.
Equally germanium and germanium oxide are transparent to infrared radiation and so are commonly Employed in the creation of spherical lenses and windows for top effectiveness infrared spectroscopes and thermal imaging techniques.
Manufacturing custom made germanium lenses for high-functionality optical apps calls for abilities in germanium optics, Highly developed equipment for instance CNC curve generators, and very controlled manufacturing processes.
