Abstract

Real world optical systems have optical components which are not perfectly aligned. The alignment errors degrade image quality.<sup>1,2</sup> The effects of expected alignment errors must be analyzed for each potential optical design to objectively evaluate its anticipated &quot;as built&quot; 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.
