Abstract
Once a Cassegrain telescope has been selected for an application, only four orthogonal parameters - back focal length, system f/number, primary mirror f/number, and system aperture diameter - need be specified in order to predict the first-order performance of the entire optical system. Frequently, one or more of these parameters, as well as the form of third-order aberration correction, are allowed as variables and, therefore, can be used to optimize the system for performance, optical tolerance sensitivity, and cost. A set of parametric equations ("K" factors) has been developed so that this optimization can be performed before resorting to any detailed optical design and the subsequent evaluation of optical sensitivity. This paper describes the variables and the parametric equations, as well as the engineering scenario into which they fit. Examples of the ways in which they are combined with structural and thermal engineering technologies to produce an optimum design are discussed.
