This paper discusses some methodologies that apply to the optical design of reflective wide-field cameras. Among the methods considered are off-axis and eccentric pupil systems, concatenation of systems, tilted component systems, aberration theory, and confocal systems. The goal of the paper is to review design methods. In particular some systems are shown to illustrate two methodologies.
