Paper Abstract

The Wide Field H-Lyman (alpha) Coronagraph/Polarimeter is currently being developed for solar research. This instrument has been designed to produce high resolution full-disk images of the Sun in a narrow bandpass centered at the neutral hydrogen Lyman (alpha) (Ly-(alpha) ) line ((lambda) 1215.7 angstroms). It has higher sensitivity and a wider field-of-view than the coronagraph which produced solar Ly-(alpha) images on May 13, 1991 during the MSSTA flight. The all-reflecting polarizers use advanced induced transmission and absorption thin film multilayer coatings to optimize the reflectivity and polarization properties at 1215.7 angstroms. We describe the instrument and discuss the current status of the fabrication of the Wide Field H-Lyman (alpha) Coronagraph/Polarimeter.
