German Infra Red Laboratory (Girl)-Liquid Helium-Cooled Infrared Observatory For Spacelab

The 40cm - telescope is equiped with an it camera, a photometer - polarimeter, an Ebert - Fastie - spectrometer, a Michelson - interferometer and a Fabry - Perot - Etalon. These focal plane instruments, covering the wavelength region between 3 and 500/μm, are under development at different institutes in Germany. Numerous observations and experiments are planned in the fields of astronomy, atmospheric physics and helium II physics. The hardware phase of the project started in November 1978, with MBB, Dornier and Linde as industrial contractors. The first flight is scheduled for the D 4 - Mission in 1983/84.
