About Fleige Optik
Fleige Optik is a fine-optics manufacturer based in Holm near Hamburg, specialising in the manufacture of optical prisms and fine-optical precision components. The product range includes prisms of all types, beam splitters, beam splitter cubes and plates, optical windows and plane-parallel plates, optical mirrors, surface mirrors, mirror polygons and optical filters – as one-off, custom and series production. Production is carried out in optical glass; raw materials such as semi-finished products, blanks and cut-to-size pieces of certain glass types are also available, in quantities of up to 100 pieces within one week. Manufacturing is performed with CNC prism milling machines in the company's own production facility; coatings such as anti-reflective and dielectric full and partial coatings are applied in cooperation with partners. Customers include medical technology (endoscopy, illumination optics, lasers, microscopy), research, telecommunications, mechanical engineering, the laser industry and automotive. The company supplies customers in Germany and internationally.

History
- 1937
Optician Konrad Fleige lays the foundation for the manufacture of optical prisms and fine-optical components.
The company is run in its fourth generation by great-great-grandson Frank Schölermann, master fine optician.
