Qioptiq employee Dr. Martin Bischoff awarded
STIFT Prize for an outstanding application-oriented thesis

Dr Bischoff's excellent doctoral thesis in thin-films earns him

STIFT Prize (Stiftung für Technologie, Innovation und Forschung

October 25, 2010

In September 2010 Dr Martin Bischoff was awarded the STIFT Prize (Stiftung für Technologie, Innovation und Forschung Thüringen) for his outstanding doctoral thesis, which he prepared at the Fraunhofer Institute for Applied Optics and Precision Engineering in Jena, as part of a joint project sponsored by the State Ministry for Education and Research (Bundesministerium für Bildung und Forschung or BMBF). The award ceremony took place on the 28th September 2010 during the Thüringen Innovation Days 2010 in Erfurt. Martin Bischoff has been an employee of Qioptiq in Göttingen since October 2009, working as a thin-film designer in the Coating Center.  

Martin Bischoff developed a process which enables the manufacture of defect-free coatings at 193 nm. In his thesis he set himself the task of optimizing the plasma assisted vapor deposition process so that metal fluoride thin films with high packing density and minimal optical losses in the deep ultraviolet spectral range (DUV) can be manufactured even at low substrate temperatures.

Qioptiq in Göttingen is using the findings of his doctoral thesis for coatings also used for longer wavelength ranges. Among other things, this innovation increases the efficiency of high-precision antireflection coatings of optical components with metal fluorides. These components are increasingly being deployed in extremely high definition photo and inspection object lenses, for example.  

Volker Brockmeyer, Qioptiq's executive vice president commented that: "the Qioptiq location in Göttingen has distinguished itself, in particular, by developing excellent skills in the coating of optical components. The coating sector is one of our core competence areas, which we will continue to expand. We are delighted that Mr Bischoff is supporting our team of experts in Göttingen and congratulate him most warmly on the award for his doctoral thesis."

Qioptiq in Göttingen currently employs approximately 160 people, 20 of whom are employed in the coating sector.
