Abstract: This manuscript introduces a method to design a freeform reflective optical system with the particularity of being aplanatic and having several stigmatic pairs. To achieve this goal the mathematical expressions in [Appl. Opt.63, 8068 (2024)APOPAI0003-693510.1364/AO.540494;… read more here.
