Paper Abstract

In this work, we discuss grid-based surface optimization in the OpticStudio lens design software. This new approach allows flexibility in designing freeform optical components that is not possible with traditional surface types. The system we focus on is a corrector plate with the rear surface specified by a variable grid sag surface. The goal of the corrector plate is to correct for wavefront error introduced by a Zernike phase surface. We optimize the sag values of the grid points to correct for this wavefront error and study the resulting behavior as the number of grid points are varied. We test grids from 5x5 to 25x25 and report the scaling of total computation time and improvement in wavefront error. We describe several findings, such as the importance of constraints on the grid variables and techniques that improve the calculation efficiency.
