A material shift in optical components from glasses to polymers has been facing a peculiar problem of larger birefringence characteristic. Birefringence causes an inherent error in optical systems Here, an optimization of various types of controllable factors is proposed toward elimination of such birefringence distributions. As a single parameter for evaluating birefringence through the design, manufacturing and m-service processes, we adopted stresses which can be converted from the stress-optical law or the Wertheim law. After formularization of the proposed method, its applicability was examined through a simple numerical simulation based on the measured birefringence distribution of an injection-molded PMMA lens. It is shown that the problem can be solved to a certain level by introducing the genetic algorithm although further controlling factors should be still considered.
