Abstract
Optically compensated refractive zoom lenses use lens groups which are mechanically coupled at a fixed separation, moving between another set of fixed separation lens groups. Such systems exhibit an image position which oscillates about a mean focal plane as the lens is zoomed. These systems are simple to implement mechanically, but they have the disadvantage that they are bulky compared with equivalent mechanically compensated zoom lens types. In a catadioptric optical system we can exploit the same sort of mechanism by moving lens groups placed between (catadioptric) mirrors, and in this case the overall system can be compact. The simplest form of system of this type consists of one lens and one mirror and this has similarities to a three-lens optically compensated refractive zoom system. In this paper the first order analysis of optically compensated catadioptric systems is given and the design of some simple representative systems are developed.
