Spectropolarimeter for the Infrared (2-8 micro).
An ir spectropolarimeter for the 2-8-micro region is described. The instrument features germanium plate polarizers, double modulation by light chopping and an oscillating polarizer, and an optical zero servosystem. The theoretical sensitivity of the instrument is derived in some detail, and the results are comparedwith the actual sensitivity of 15 mdeg.
