1995 - 2005
The Gallium-Arsenid infrared detectors were a development for the far infrared and should have been used on the infrared telescope onboard the SOFIA airplane and on the ESA satellite Herschel (aka FIRST). During the long development phase it turned out that the production of the extremely pure GaAs material was very problematic. Also, MPE interest in developments in the far infared regime changed and the project was abandoned at MPE.
