title: GEMINI spectrograph optics.
abstract: In this paper the optical system design of one of the spectrograph instruments to be employed in the General Excitation Mechanisms in Nightglow project is described. The instrument has a high throughput with a numerical aperture equivalent to ƒ/1.7 and covers the spectral range from 255 to 327.5 nm. A 3-deg line in the object space is imaged onto a two-dimensional intensified CCD array with spatial and spectral resolutions at least matching those of the detector.
