Extreme ultraviolet spectrometer for space research.
A normal incidence spectrometer for use in the wavelength region from 200 A to 1270 A has been developed. The design and calibration of the instrument are described in detail. The spectrometer can be employed to detect extreme uv radiation at a minimum flux level of 1 rayleigh with a spectral resolution of 40 A and a spatial resolution of 6 degrees . Data on the extreme uv night sky spectrum between 780 A and 1270 A obtained with this instrument on a recent rocket flight are presented.
