A Simple Key For optical germanium lens Unveiled
Blog Article
Plano-convex Ge lenses are flat on a single facet and convex on one other. These lenses Have a very optimistic focal length, and will often be employed for mild collimation.
Our spherical plano-concave germanium lenses are largely utilized to diverge a beam from the collimated gentle resource, or to improve the focal duration of the optical method.
Count on our gifted crystal growth specialists to overcome these troubles and supply demanding specifications.
If significant transmission is the only real consideration, you’d be ideal served to double coat your Home windows with BBAR over particular wavelength ranges and you'll see transmissions every one of the way nearly 99%. Now we’re chatting!

Welcome to UQG Optics! It looks like you're visiting in the US. Decide on your most popular forex below to find out acceptable pricing. Call us For added guidance or to discuss particular specifications.
Both of those monocrystalline and polycrystalline Ge could be useful for manufacturing of optical elements. We create Germanium lenses and Home windows for infrared thermal imaging applications and pyrometry (see our webpage Germanium Home windows and lenses for thermography).
Click the different category headings to determine extra. You can also modify several of your Tastes. Take get more info note that blocking some sorts of cookies may effect your knowledge on our Web-sites and the providers we have the ability to offer you.
Regularly, DLC coatings tend to be paired with Broadband AR Coatings (BBAR) to not simply up the mechanical functionality but also the transmission Qualities. Normally, a window is coated on just one side with DLC and the other side with BBAR (usually inside the 7-14μm variety to boost both of these properties in tandem.
It could be Reduce, polished and formed into lenses and Home windows Utilized in infrared detector tools in addition to infrared spectroscopes.
At Shanghai Optics we manufacture a wide variety of germanium lenses with various anti reflection coatings. Spherical plano-concave, p-convex, concave-convex and aspheric lenses are all offered in lots of dimensions. We will also be equipped to accommodate special orders do you have to have to have a measurement, condition or AR coating.
Sharpening & coating: Our sprucing strategies provide Outstanding amounts of flatness, surface area roughness, and surface excellent. Germanium lenses normally need optical or anti-reflection coatings to further improve their performance and longevity.
Production custom made germanium lenses for prime-functionality optical applications calls for experience in germanium optics, advanced devices including CNC curve turbines, and very controlled producing processes.
Germanium was initially employed on a large scale to interchange One of the more primary Digital factors, the diode.
