Paper Abstract

Specific needs of a given lens design may significantly affect what is an "optimum" design. A manufacturing process, the intended production quantity, or an unusual customer requirement, for instance, may dictate that the designer use a different merit function than that employed in the optimization program. This paper presents the results of using a new tolerance sensitivity program, ZEST to address the change in merit function. The results include reducing the sensitivity of a lens to manufacturing perturbations, particularly to tilts and decentrations. Other improvements are achieved such as reduced astigmatism and increased axial MTF. A lens designed using a conventional optimization program is evaluated and tuned up by use of the technique.
