Our germanium lenses Possess a higher refractive index—the highest refractive index among the readily available IR transmitters. Furthermore, it exhibits minimum chromatic aberration resulting from very low dispersion.
Germanium is also matter to thermal runaway. What This suggests is that the transmission will decrease as temperature raises, and the lens becomes opaque. For that reason thermal runaway impact, germanium lenses should only be employed at temperatures down below a hundred°C.
Germanium has outstanding thermal steadiness. It may endure large working temperatures without having degrading optical efficiency.
You undoubtedly don’t need to breathe in germanium dust so care has to be taken although dealing with these optics. Making use of gloves Anytime probable and washing arms must be Section of any conventional running procedure.
Our metallic or dielectric coatings on mirrors are optimized to meet your prerequisites. Simultaneously, these coatings protect the elements towards environmental effects and enrich the reflection. Jenoptik checks all components in accordance with DIN ISO or MIL benchmarks.
Our in dwelling generation capabilities enable us to provide fast guide-times and top quality material at competitive selling prices. We manufacture both equally common evaporation sizes and custom made dimensions on request...
The end intention is to create germanium optics that meet up with or exceed the demanding demands of varied purposes, from infrared thermal imaging and sensing to spectroscopy and laser systems.
Hi, I'm your Digital assistant, I will do my best possible that can assist you navigate all factors Fluke related. You could talk to me everything! I am new and may well make a several blunders.
Firebird Optics manufactures these kinds of windows in different geometries, coatings and might also produce lenses, prisms and numerous other optical components from germanium. Now again on your frequently scheduled programming…
At Shanghai Optics we manufacture a wide variety of germanium lenses with many anti reflection coatings. Spherical plano-concave, p-convex, concave-convex and aspheric lenses are all available in numerous types of dimensions. We can also be capable to accommodate Particular orders do you have to have to have a dimensions, condition or AR coating.
Coatings from Jenoptik let you guidebook beams in the specific way. They filter specific wavelengths, replicate optics or redirect them and lessen reflection if necessary. We optical germanium lenses offer the next:
Rather than needing multiple different cameras to complete all of these jobs, you can save some huge cash with “smart” insert-on lenses that may be utilized between several compatible cameras with no special recalibration for each digital camera and be capable of quickly swap out lenses on the job.
Uncooked germanium material is very really hard but can still effectively be machined and polished into optical parts:
