Precision optics

As a supplier precision optics, COTEC is a company with a global reach. We contribute to value creation in our industry with our high purity vaporizing materials and protective easy-to-clean coatings from the DURALON product range.

Our clients can enjoy highly pure vapor deposition materials in customer-specific packaged forms which meet individual customer requirements. The sputter technology field is covered by our sputter targets which we manufacture in-house according to customer specifications.

In order to protect the sensitive precision optics, our DURALON products include functional coating materials allowing for a final tempering of the components without altering the optical properties. In addition to easy cleanability, the coating also offers protection against extensive mechanical wear.

Combined with the HSC series vapor deposition equipment, especially developed for the DURALON coating, we provide our customers a full package for functional coating.

Our quality management includes not only data sheets and certificates, but also our own test equipment for verifying material composition and purity in order to carry out detailed and reproducible testing of the coating.
