The virtual product development of optical design with Ansys SPEOS can be accelerated by Ansys optiSLang’s robust design optimization approach. Optical designs can be explored thoroughly by means of sensitivity analysis. This includes the identification of relevant input parameters and the modeling of inputs vs. outputs to understand their dependencies and interactions.
Furthermore, the intelligent definition of objective functions for an efficient subsequent optimization is of high importance for multi-objective optimization tasks. To find the best trade-off between two or more merit functions, a Pareto optimization is the best choice. As a result, several best designs are obtained, and the most appropriate one can be selected by the decision-maker.
Additionally, the best trade-off between output variation of the robustness (tolerance) analysis and optimization targets can be found to secure the manufacturability of the optical design by several advanced approaches. The benefit of the robust design optimization approach with SPEOS and optiSLang will be demonstrated.
