Paper Abstract

The optical design, test, and fabrication of a large ultra lightweight flat beryllium scan mirror is reported. The mirror is a key component for the (TIR) thermal infrared radiometer instrument which is scheduled to compliment the (EOS) Earth observation satellite program. The unique optical design properties of the mirror provide state of the art performance for scan operations and thermal imaging of the earth's surface in the 8.0 to 12.0 micron wavelength range. The mirror's opto-mechanical design provides a very stable non-deformed platform for the scan drive system. The mirror's optical figure, surface characteristics and protected gold coating have been tested and are well within the flight specifications.
