Ranging from array projectors in the automotive sector to 3D real-time scanners in production and quantum technologies for tap-proof communication, the Fraunhofer - Institute for Applied Optics and Precision Engineering IOF develops innovative solutions with light for a wide variety of applications. To cover the entire photonic process chain, we use our comprehensive competencies in the areas of optical and mechanical system design, micro- and nanostructured optics, opto-mechatronical as well as precision optical components and systems, functional surfaces and coatings, laser and fiber technology, imaging and sensing technology and optical quantum technologies. Innovative solutions arise that open up new fields of application for photonics in science and industry.
