Coating Materials

Various types of optical coatings are needed e.g. in AR, for mirrors, or filters. Specifications can be crucially demanding, with tight spectral tolerances, low defect densities, and high durability requirements. To develop your coating production, our consistent "High-Purity" materials can be produced on your demand.
