Our spherical plano-concave germanium lenses are mostly used to diverge a beam from the collimated gentle source, or to enhance the focal duration of an optical system.

Germanium can also be topic to thermal runaway. What This suggests is that the transmission will reduce as temperature boosts, and also the lens results in being opaque. For that reason thermal runaway influence, germanium lenses really should only be made use of at temperatures below one hundred°C.

Jenoptik manufactures hybrid parts in optical substance for infrared apps. They are perfect for infrared aim lenses and programs, and also for image capture, concentrate on detection and in infrared camera technologies. You can Select from concave, convex, aircraft, spherical and aspherical surfaces. Data Sheet

Our metallic or dielectric coatings on mirrors are optimized to satisfy your requirements. Simultaneously, these coatings guard the factors against environmental influence and boost the reflection. Jenoptik assessments all parts in accordance with DIN ISO or MIL criteria.

Germanium lenses are optical lenses made of polished germanium. Germanium Optics are rugged and proof against corrosion, and are ideal for severe environments and programs where There may be continuous publicity to The weather.

By growing an individual crystal, we produce elements which has a constant crystal construction and superior purity.

Germanium incorporates a high refractive index, get more info so lenses made from Ge can target mild extra efficiently and produce higher-resolution imaging which include thermal cameras, remote sensing, and night eyesight products.

The sharp transmission Minimize-off prior to twoµm also permits germanium to be used as a protracted go filter, only transmitting wavelengths in extra of twoµm and fully blocking all the things just before it.

They could be used in beam expanders, and can be utilized to equilibrium out aberrations which had been launched by other lenses within an optical arrangement.

Including an aspheric lens into an optical assembly has the prospective to considerably simplify the system, and in some cases the addition of reasonably significant germanium lens may well basically minimize the units weight.
