Abstract

Computer programs for automatic optimization of optical designs provide numerous opportunities for production cost reduction. Some of these opportunities have been exploited heavily. For example, many manually designed systems have been replaced with less complex systems of comparable performance, designed with the aid of such computer programs. Cost sensitive parameters such as blocking factors, diameter to thickness ratios, and sharp diameters are readily controlled within automatic optimization procedures. Additional opportunities for savings are available. Convertible and multi-channel systems are commonly comprised of individually well-corrected modules. Several computer programs now have the ability to optimize the various configurations of such multi-configuration systems simultaneously, leading to a potential reduction in complexity for such systems. Options to control and reduce sensitivity to manufacturing errors as part of the optimization process are used infrequently, despite the fact that these options have produced dramatic solutions to several disastrous manufacturing problems. In more routine designs the worst sensitivity may be reduced on the order of one half, leading to worthwhile manufacturing economies. Illustrative examples are presented.
