The project PluTO+, Plasma and Optical Technologies: increasing the Quality and Effect of Optical Coating Technologies was launched in October 2014 to research new production methods for the modern optics industry. This project unites industrial companies and research institutes and is funded by the Federal Ministry of Education and Research (BMBF) with a total of €9.5m across a time span of three years.
This project is part of a series of research projects under the BMBF funding initiative The Basis of Photonics: Functional Layers and Systems. LASER COMPONENTS is participating as an active industrial partner in the research and development of new ground-breaking technologies.
The aim of the project is to improve process stability during the production of optical coatings through the characterisation and control of the plasma processes used.
The work is focused on the production of optical elements in the infrared range at 2.1 and 2.9µm. The physical processes in the ion sources of two LC coating systems are currently being examined in detail using plasma diagnostic methods. Based on this study, a control system is being developed that makes it possible to increase control of the coating process and improve product quality.
