A satellite-borne extreme-ultraviolet airglow spectrometer is described covering the 275-1420-Angstroem range with 8-Angstroem resolution. The spectrometer is of near normal incidence Rowland circle design and employs a holographically ruled concave grating. The detector is a microchannel plate with resistive anode providing a continuous readout of any 650-Angstroem ground-commandable subset of the total bandpass. This simultaneous wide spectral coverage results in a factor of 80 increase in sensitivity over a fixed exit slit design of equivalent resolution.
