Lens parameters optimization sensitivity prediction using Ansys Zemax multi-configuration composite feature

The merit function defines the permissible range of component variable values in optimizing lens systems. This ensures the optimization algorithm explores parameter variations within specified bounds, contributing to the generation of feasible designs. In this study, we introduce an approach to identify the optimization-sensitive surface parameters of a relay lens through the utilization of the multi-configuration composite feature. The parameter variations sensitivity is analyzed by employing the Zernike Standard Sag Surface as an add-on composite surface, with a perturbation pattern of spherical aberration irregularity across multiple configurations preceding each lens surface within the Zemax lens data editor. The primary performance degradation impact on surface parameters is identified by examining the image spot dimension charts. In light of the analysis results, rigorous constraints are imposed on the sensitive component. A suitable variable range is defined to establish practical limits, aiding the algorithm in searching for solutions within the feasible parameter space. This ensures optimized designs that are physically realizable and meet the specified performance criteria.
