Abstract

Freeform technology is one of the most promising solutions to enhance the performance of optical systems. Aiming to demonstrate the freedom and flexibility of optical system design, several challenging design examples using freeform surface are presented, including two wide-angle camera lenses adopting even and odd pedal polynomial formulations for symmetric optical surface description, and an anamorphic cinema lens employing non-rotationally symmetric surfaces for capturing a wider aspect ratio and offering a 1.33X squeeze factor on a 4:3 sensor size. Methods and constraints for designing and optimizing the optical systems are discussed. The optical performances of these design examples are analyzed. The results verify the practicability and effectiveness of the proposed formulations and design strategies in the field of freeform imaging optical design.
