Abstract

The paper discusses the problem of designing the aspheric surface of a Schmidt camera so as to obtain optimum performance, in an agreed sense, over the field taken as a whole. A solution is obtained in a form which allows the optimum plate-profile to be quickly determined for a Schmidt camera of given aperture-ratio and field-size, working over a given spectral range. It is shown that at apertures near f/3 the optimum plate can be obtained by slightly decreasing the strength of an ordinary “color-minimised” Schmidt plate, while in wide-field systems working at apertures near f/1, it is better to use a plate with neutral zone at the edge of the aperture.
