At home in Westerwald.

Our know-how for you.

As a developer and manufacturer of sophisticated technical components, and as one of the market-leading and most innovative vacuum coating companies, Bte has been valued since 1992 by well-known customers from a wide range of industries at home and abroad. Short paths, fast responses: a lean organization, flat hierarchies, efficient use of resources and service-oriented business processes make us so flexible.

Thin coatings in large dimensions.

Glass, metal and plastic – there is probably hardly any surface that we have not yet coated. And without being aware of it, you will have almost certainly come across us already – for example, in the form of operation lamps, head-up displays, headlights, optical sensors or UV reflectors. So if you're looking for optical components with coatings, Bte is the place to go. Well-known providers from a wide variety of industries associate mirror plating and anti-reflection coatings, optical precision filters, beam splitters and much more with Bte.

Any components which can be manufactured with vacuum coating can be fully designed to your requirements - from large batch production through project business for astronomy and science to individual small orders.
