Model-based coating of 3D components
Optical functions – e. g. anti-reflective coatings or filters for specific spectral ranges – can be realized by means of interference coating systems. These systems deploy a sequence of high and low-refractive layers whose layer thicknesses are precalculated according to the desired optical function. At the Fraunhofer IST, such coating systems are produced by means of magnetron cathode sputtering; applications are optical components in the field of precision optics.
