Abstract

We have designed a grazing incidence spectrometer to measure the diffuse astronomical background between 80 and 650A. The instrument uses a wire grid collimator to define a 40' by 15° field of view. After passing through the collimator, radiation impinges on an array of plane reflection gratings. An array of mirrors then focuses the diffracted light through a thin filter onto a microchannel plate detector. The resulting system focuses to a few arc minutes and produces spectra with 10 to 20Å resolution. The instrument is currently undergoing integration for flight in 1986. Performance characteristics of the spectrometer are discussed.
