Interference coatings play a key role in many optical instruments whenever light has to be transmitted or formed, e.g. with anti-reflective coatings, optical filters, beam splitters, or polarizers. mso jena develops and manufactures optical components with interference coatings individually optimized for every single application. This capability is founded on many years of experience, sophisticated thin-film design software, up-to-date deposition technology, and a highly skilled staff.
