optical germanium lens - An Overview
Blog Article
Lattice Resources is exceptionally equipped to make optical components, and germanium lenses especially, to specific optical technical specs with any ending you call for.
For a complete breakdown of how you can wade through each of the important optical window alternatives check our optical window tutorial.
Additionally it is worthy of noting that germanium is relatively additional brittle that silicon and thus ought to be deal with with care all through machining.
Germanium has exceptional thermal steadiness. It could face up to superior operating temperatures with no degrading optical performance.
No water solubility- advantage above salty windows for instance KBr and NaCl that are incredibly hygroscopic.
An additional consideration is germanium’s density. At 5.33g/cm3 it does not float like a butterfly and sting like a bee. It’s hefty. Very weighty and this could should be viewed as when building pounds-delicate programs.
Actually, at a watch-popping Knoop Hardness of 2000kg/mm2, one particular may well question, why wouldn’t I just use sapphire Home windows as opposed to germanium? When sapphire is the undisputed winner of robust optics in the UV/VIS and mid-IR with a wavelength vary that dips in the much UV range at 150nm, it may possibly only be applied approximately four.
When not in use, we advocate storing your germanium Home windows wrapped in lens tissue with humidity underneath thirty% and involving 15 and 25ºC. While germanium is really challenging things, these are generally The best problems that can lengthen the lifestyle of one's window.
Similar to how noticeable mild digital camera lenses undoubtedly are a solid glass form, thermal digital camera lenses are reliable Germanium. Equally as glass is clear to seen gentle, Germanium is transparent on the wavelength band of infrared radiation, which most thermal cameras use.

At Shanghai Optics we manufacture a wide variety of germanium lenses with several anti reflection coatings. Spherical plano-concave, p-convex, concave-convex and aspheric lenses are all out there in lots of measurements. We can also be capable to accommodate Unique orders in the event you need a size, condition or AR coating.
Jenoptik´s OrthoLine optical alignment cubes are designed generally for processes that require precision datum registration - more info such as applications from the lifestyle and health and fitness sciences, metrology and protection.
UQG Optics most effective-sellers like Germanium Windows are available coated and uncoated in a variety of diameters and thicknesses.
Optical precision is vital to meet certain needs connected with accuracy, surface area high quality, and All round optical efficiency.
