Michigan Aerospace has an extensive history in the field of tunable Fabry-Perot etalon and interferometer technology. This history began in 1987 with the High Resolution Doppler Imager (HRDI) flown on the Upper Atmospheric Research Satellite (UARS).

Michigan Aerospace stays on the cutting edge of Fabry-Perot technology, producing tunable etalons for both ground and space-qualified applications. Our engineers and scientists design etalons and interferometers for challenging cryogenic and high vacuum environments using the most advanced, light weight casting and machining technologies available. In addition, Michigan Aerospace etalons and interferometers are engineered for the challenging dynamic vibration conditions found aboard aircraft.
