Scientific paper

Although previous work has emphasized the usefulness of gratings placed at grazing incidence in converging beams for extreme ultraviolet astronomy specific applications may well require a design that can be placed behind a slit at the prime focus of a telescope. The authors have designed a grazing incidence spectrometer that accepts a diverging beam and performs moderate resolution spectroscopy. They limit their analysis to an extreme ultraviolet spectrometer covering the 100 to 350 Å bandpass. An optimum design is found by varying six parameters and maximizing the average resolution over the bandpass, assuming a telescope blur of 75 microns (corresponding to 1arcsec.5 at the focus of a telescope with focal length 10 meters). The resolution of this optimized design varies from 300 to 800 across the bandpass. The spectrometer can be located far from the optical axis of the telescope and fed by a small grazing incidence pick-off mirror.
