Method of discontinuous optical glass optimization based on aberration correction in optical design

Optical glass selection is an important research object in optical design, which is an important way to aberration correction. However, these methods to our knowledge either do not correct aberration well or consume too much time. To efficiently solve the apochromatic problems in optical design, this paper presents what we believe to be a novel automatic optimization method for discontinuous optical glass based on auto glass selection (AGS). The method first calculates several aberrations related to glass materials in the optical system to select candidate optical glasses, which include longitudinal aberration, lateral chromatic aberration, and Petzval sum. It then skillfully explores the candidate optical glass list for the optimization of discontinuous glass. Using a flat-field apochromatic microscope and a wide-angle lens as examples, this method demonstrates its superiority in aberration correction and efficiency, can be automated optimization, requires relatively less computational effort, and achieves fast and stable convergence of results.
