Michigan Aerospace's staff has been developing Fabry-Perot interferometers since the 1970's, with the FPI flown on Dynamics Explorer-2 and the High Resolution Doppler Imager (HRDI) flown on the Upper Atmospheric Research Satellite (UARS), still in operation today. Our etalons can be fabricated for use with wavelengths from the UV to the far IR, are suited for use in high vacuum and/or cryogenic environments, and can be qualified for spaceflight or airborne applications. We are capable of designing and fabricating etalons with clear apertures of up to 150 mm and optical air gaps of up to 80 mm. Room temperature tuning ranges for our etalons can range from 2-5 microns with ceramic piezoelectric actuators to up to 50 microns using ferroelectric single crystal actuators. Cryogenic tuning ranges of up to 25 microns can be achieved with the use of ferroelectric actuators.
