Precision optical coatings are key technologies for modern optical systems. These complex coatings impose stringent requirements for uniformity, process stability and productivity on an industrial scale. Stefan Bruns, Philipp Farr and Michael Vergöhl from the Fraunhofer Institute for Surface Engineering and Thin Films IST in Braunschweig have developed a unique coating technology for precision optics systems that meets these requirements and is already in use in industry. Their efforts have earned them the Joseph von Fraunhofer Prize for 2026.
