Abstract

A monocentric element, that is, one whose surfaces are concentric, can be valuable in an optical design. Such elements are, however, very difficult to fabricate. A departure from true monocentricity will make the fabrication problem more tractible and can usually be achieved without loss of design performance. A relationship is derived which will indicate the minimum departure from monocentricity necessary to make fabrication feasible.
