Abstract

Parameters are given for a corrector lens design which will provide a 0.5 degree field of good definition from 134nm to 280nm at the Ritchey-Chretien focus of the F/2-F/15 Starlab 1-metre telescope. The optimization includes the window of the detector which is aspherized on the outside but not on the inside where the photocathode is deposited. The 130 mm diameter detector is preceded by two lenses, the first of which is convex-plano. Because this element has a flat surface it can be interchanged with other elements to either compensate for the chromatic aberration of filters (by making the lens thinner), and/or to provide dispersion for multi-object slitless spectroscopy. In the latter case, the interchanged element is wedged and has a course transmission grating deposited on the flat side. This combination of grating and lens is referred to as a grens.
