In this paper we describe an optical system with one surface aspherized to give a specific level of performance and to equalize the intensity profiles of star images over the field. The system was a 25.4-cm EFL, 5.80° field, ƒ/1.53 catadioptric Cassegrain. It was designed to determine the attitude of a space platform by detecting and mapping the geometric pattern of stars observed to ninth visual magnitude. Aberrations were controlled over a 0.5–1.1-µm spectral region. We compare the polychromatic performance of our design to one conventionally optimized. We also describe how the spherical substrate base radius was chosen to minimize glass removal.
