Centre of Competence for Laser, Optics, optical Technology and Systems (LOTuS)

The Centre of Competence for Laser, Optics, optical Technology and Systems (LOTuS) brings together all the research and development work in the areas of optics and optical technologies in the departments of Information Technology-Electrical Engineering (IEM), Mathematics, Natural Sciences and Data Processing (MND), and of the Optics Center in Wetzlar which conducts application-oriented research on optical technologies together with cooperating regional optics companies.

The optical measurement technology and sensors developed are used, among other things, in the monitoring of automated manufacturing processes in the field of Industry 4.0. The same applies to the additive manufacturing of metallic components with high structural resolution using the LPBF (Laser Powder Bed Fusion) method, which meets the high accuracy and surface requirements of optical elements. In addition, developments in artificial intelligence, autonomous mobility, miniaturisation and lightweight structural engineering in particular offer promising potential for innovations and new developments in the field of optics, as they are largely determined by optical systems and optical measurement or manufacturing processes.
