Telescope lenses for high-energy laser PHELIX

For more than 20 years, research has been carried out at the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt on the development of a high-power, high-energy laser for fundamental research in the field of high-energy physics. The result is PHELIX (short for Petawatt High Energy Laser for Heavy Ion Experiments), which is used to investigate fundamental processes in plasma physics, astrophysics and atomic physics.

Optics for Sentinel-5

For the analysis of atmospheric components such as O3, NO2, SO2, etc., ESA initiated the Sentinel-5 project together with the European Union. A central objective of the missions spectrometer system, which is expected to be deployed on the MetOp-SG A spacecraft from 2022 onwards, is the monitoring of trace gas concentrations. asphericon manufactured durable optics for one of the subsystems of Sentinel-5.
