Abstract
A plane-grating spectrograph using a movable calcium fluoride camera corrector lens has been designed and constructed. It can be used to cover a wavelength range from about 12 000 A to 1500 A. The dispersion is approximately 58 A/mm, in the first order. The camera focal ratio of f/2 gives the instrument a speed such that for relatively weak sources, the exposure times have been reduced from several weeks to a number of hours.
