This is MICROS Optics
MICROS Optics is an owner-managed manufacturer of precision optics based in Schmiedefeld (Saalfeld), Thuringia, since 2001. The company manufactures flat optics such as flat plates, filters, mirrors, prisms, wedge plates, light guides and beam splitters, spherical optics such as lenses, achromats and cylindrical optics, refined technical glasses as well as optical thin films ranging from anti-reflective coatings to mirror, filter and beam splitter coatings, and also conductive transparent coatings (ITO). The portfolio is complemented by mechanical glass processing with CNC cutting, waterjet cutting, sawing, CNC milling, grinding and polishing, thermal and chemical toughening of glasses, as well as assembly of optical assemblies and systems. Optical components are manufactured with edge lengths from 0.5 to over 3,000 mm. On request, contract coating is carried out on substrates supplied by the customer. Products made from materials such as optical glasses from SCHOTT and OHARA, fused silica, borosilicate glass, sapphire and glass ceramics serve photonics, laser technology, medical technology, aerospace, sensor technology as well as the semiconductor and microscopy sectors. Worldwide delivery is made exclusively from German production at the main site in Schmiedefeld; a sales office in Rennerod (Rhineland-Palatinate) serves the customers. The company is certified to DIN EN ISO 9001.
