Abstract
Two sounding rockets payloads under development at the Space Astronomy Laboratory are intended to explore different forms of ultraviolet astronomical polarimetry as a follow-up to the successful mission of the Wisconsin Ultraviolet Photo-Polarimeter Experiment (WUPPE). The unknown territory of diffuse-object ultraviolet polarimetry is to be explored by the Wide- Field Imaging Survey Polarimeter (WISP). WISP is a quite unusual integrated fast telescope/polarimeter optimized for the wavelengths 135 - 260 nm. The first WISP flight is scheduled for Fall 1993, targeting the Pleiades reflection nebula. Just in its early development is another sounding rocket payload, the Far-Ultraviolet Spectropolarimeter. This instrument is to have a resolution of better than 0.1 nm and a spectral coverage from 105 to 145 nm. It will consist of a 0.4 m parabolic primary with polarimetric optics at the prime focus and a far ultraviolet spectrometer. The polarimetric analyzer will be a thin stressed-LiF waveplate, followed by a diamond Brewster-angle polarizer.
