This paper describes the infrared spectropolarimeter currently under development at the University of Alabama in Huntsville. The instrument, the data acquisition and processing algorithms, and several calibration issues are examined. Results are presented showing measurements of the retardance spectra of polarization elements, and the s- and p-transmission and diattenuation spectra of infrared coatings.
