Real world optical systems have optical components which are not perfectly aligned. The alignment errors degrade image quality.1,2 The effects of expected alignment errors must be analyzed for each potential optical design to objectively evaluate its anticipated "as built" performance. The value of using optical alignment tolerancing as a figure of merit in the optical design phase of a catadioptric lens is demonstrated. The result is a high performance optical system which can be sized for hand held airborne reconnaissance or long range spaceborne reconnaissance. The effects of sizing on alignment tolerance are presented.
