Our metallic or dielectric coatings on mirrors are optimized to satisfy your necessities. Concurrently, these coatings protect the elements from environmental impression and enhance the reflection. Jenoptik tests all elements in accordance with DIN ISO or MIL standards.
It's the Specific hardness of germanium that provides it its unique ruggedness; Ge includes a Knoop hardness of 780. It's a higher density material, at 5.33 g/cm3, and allowances has to be produced for this excess weight Should you be planning a body weight sensitive process.
Germanium lenses are optical lenses manufactured from polished germanium. Germanium Optics are rugged and resistant to corrosion, and are ideal for harsh environments and apps the place There may be continuous publicity to the elements.
We offer precision cylinder lenses in round, rectangular or quadratic designs to fulfill your specifications. The optical components can be obtained with significant-reflection or antireflection coatings to the DUV, UV, VIS and IR spectral ranges. The Distinctive coating improves the cylinder lenses and will make them much more resistant. Information Sheet
We also recycle evaporation quality products from coating amenities. Novotech is also acquiring several semiconductor substrates and components, which we're changing back into their first elements.
At Shanghai Optics we manufacture numerous types of germanium lenses with different anti reflection coatings. Spherical plano-concave, p-convex, concave-convex and aspheric lenses are all available in lots of dimensions. We can also be capable get more info to support Unique orders in case you have to have a dimension, form or AR coating.
Germanium and germanium oxide have an incredibly substantial refractive index, meaning that for a few window applications anti-reflective coating is needed.
