Founded in 2004, the Chair for Technology of Optical Systems is part of the faculty of mechanical engineering at RWTH Aachen University. It is one of three chairs LLT, TOS and NLD which are located in the building of the Fraunhofer-Institute for Laser Technology.


Head of Chair
Professor Carlo Holly is the Head of Chair.

The premises
The chair is located in the ILT and works in close co-operation and coordination with the Fraunhofer ILT. A comprehensive technical equipment and substantiated know-how are available for research and development.

The chair carries out research and development in the areas of optical systems for lasers and laser applications, Computational Optics and EUV Technology.

Research is embedded in several projects funded by third-parties such as the German Research Foundation (DFG) and the European Union (EU). A few selected research projects are presented briefly.


The chair offers lectures in the Bachelor's and Master's programme about the Technology of Optical Systems.
Professor Loosen and his team were awarded the Internal Faculty Teaching Award (de) for the courses they held in summer semester 2013. The Faculty for Mechanical Engineering of the RWTH Aachen University awards an Internal Faculty Reaching Award (de) for excellent teaching in an internal faculty comparison since 2013.
