Paper Abstract

X I present a new design for a moderately high resolution (λ/Δλ = 103) nebular spec-AX. trometer incorporating a mechanical precollimator with an objective Echelle grating followed by a cross-dispersing Wadsworth configuration. The design uses the minimum number of reflections to maximize extreme ultraviolet reflectivity, and yields a relatively large field of view for optimal sensitivity to diffuse emission. The configuration is compact, uses conventionally fabricated optical components and existing microchannel plate detectors, yet achieves sensitivities near the limit imposed by Liouville's theorem.
