Instrumentation development for the European Southern Observatory ESO / Garching

• MICADO - the 1st Light Camera at the 39 m E-ELT
• 4MOST - 4-metre Multi-Object-Spectrospic Telescope
• MOSAIC - Multi Object Spektrograph, "working horse" at the E-ELT
• ERASMUS-F - precursor study for the E-ELT
• MUSE - D3Dnet Spectroscopy at 16 m VLT
• OmegaCAM - the Gigapixel Camera at the ESO VLT-Survey-Telescope
• FORS1 und FORS2 - the Twin Focal Reducing Spectrographs of the ESO/VLT

Telescope and Instrumentation development for further Observatories

• LRS - Low Resolution Spectrograph at the Hobby-Eberly-Telescope/Texas
• GREGOR - the 1.5 m solar telscope in Izana/Teneriffa
• MONET - monitoring network of two 1.2 m telescopes at the McDonald Observatory/Texas, and the South African Astronomical Observatory/South Africa
• VVT - Vacuum vertical telescope at the Institute for Astrophysics/Göttingen
• CASS - 50 cm Cassegrain Telescope at the Institute for Astrophysics/Göttingen
• DGT - Designstudy of a 12-m optical Telescope DGT for the Astronomy in Germany
