Germanium has fantastic thermal balance. It could endure substantial operating temperatures without degrading optical general performance.
No h2o solubility- gain about salty windows for instance KBr and NaCl which can be extremely hygroscopic.
Watchful dealing with and cleansing: Germanium optics are particularly tough and brittle. Good cleansing and packaging strategies lower any problems or contamination which could influence its optical performance.
Our in residence production capabilities enable us to supply swift direct-situations and high quality content at aggressive charges. We manufacture each common evaporation dimensions and customized sizes on request...
Germanium’s transparency during the infrared wavelengths make it a vital and commonly applied product in infrared optics.
Coatings: Specialized anti-reflective coatings and treatment plans can even further boost the overall performance of germanium optics here by lessening reflection and absorption, strengthening transmission, and growing toughness.
Apparently, as a result of its identical crystal structure to Diamond is usually coated using a DLC layer (Diamond Like Carbon) which along with lessening the reflection on it’s surface area, adds a diamond solid protecting layer. Finally Germanium just isn't transparent inside the seen which may be handy to deal with IR gentle.
At Shanghai Optics we manufacture numerous types of germanium lenses with various anti reflection coatings. Spherical plano-concave, p-convex, concave-convex and aspheric lenses are all accessible in a wide variety of dimensions. We are equipped to support Specific orders in case you require a dimension, condition or AR coating.

UQG Optics very best-sellers for example Germanium Home windows can be obtained coated and uncoated in many different diameters and thicknesses.
Incorporating an aspheric lens into an optical assembly has the possible to greatly simplify the process, and also the addition of relatively weighty germanium lens may in fact decrease the programs weight.
