Our germanium lenses Have a very high refractive index—the very best refractive index among the readily available IR transmitters. In addition it displays nominal chromatic aberration resulting from reduced dispersion.
It is also worth noting that germanium is fairly extra brittle that silicon and so really should be manage with treatment for the duration of machining.
Germanium has exceptional thermal steadiness. It can face up to higher functioning temperatures without having degrading optical overall performance.
You surely don’t would like to breathe in germanium dust so care must be taken though handling these optics. Utilizing gloves whenever feasible and washing hands should be part of any conventional operating procedure.
Be sure to bear in mind this may well heavily decrease the operation and overall look of our web site. Changes will just take effect when you finally reload click here the webpage.
Shanghai Optics manufactures top quality germanium lenses in A variety of well-known sizes, from 5m m to 350 mm in diameter.
Novotech is a global provider of evaporation grade Germanium. We aid IR coating businesses along with the fiber optics marketplace with their material requirements.
Hi, I'm your virtual assistant, I'll do my easiest that will help you navigate all issues Fluke associated. You'll be able to question me everything! I'm new and may make a few mistakes.
Just one very common scenario we see germanium used is inside high and small pace wind tunnels for jet propulsion scientific studies. Usually, these Home windows are much larger than inventory configurations reaching dimensions in extra of 190-200mm.
Ge lenses can transmit infrared wavelengths without the need of substantial loss, allowing for for clear and accurate imaging.
Jenoptik´s OrthoLine optical alignment cubes are designed largely for procedures that demand precision datum registration - including programs during the existence and health sciences, metrology and defense.
Product Variety: Substantial-quality germanium substrate is essential for making superior-functionality lenses, as any defects or impurities while in the germanium crystals could influence the optical Homes with the finished lens. Rely on Lattice to offer superior-grade tailor made-developed germanium to be certain superior-quality lenses.
Uncooked germanium have a comparatively normal transmission from the IR (a lot less than fifty%) but Anti-reflect or DLC remedies do enhance a great deal it’s transmittance.
