We present optical data on prototype polarization sensitive Argonne/KICP detectors fabricated at Argonne National Labs which are designed to be installed on the South Pole Telescope and used to measure the polarization of the Cosmic Microwave Background radiation. The detectors are Mo/Au transition edge sensors (TES) suspended on silicon nitride, with radiation coupled to the TES using a gold bar absorber. Two stacked detectors with bars in orthogonal directions will be used to measure both polarizations. We discuss measurements of the optical bandpass, time constants and cross-polarization of the detectors.
