Paper Abstract

We present an instrument design for imaging spectroscopy in the far ultraviolet (FUV, 912- 1250 angstrom) and the extreme ultraviolet (EUV, 100-912 angstrom). The design consists of a collimator and telescope to collected light, an aberration corrected planar holographic grating placed directly in the converging beam of the telescope, a transfer mirror, and a microchannel plate detector. The design provides spatial on the order of 10 arc seconds and is limited by telescope blur and detector resolution, not by grating-induced aberrations. The spectral resolution is approximately 1000 for point sources and greater than 30 for diffuse objects which uniformly illuminate the 10 arc minute collimator.
