Optimum solution for spherical primary mirror with two and three aspheric corrector plates located near focus. Part 2.
The case for two aspheric plates is further investigated to include ray trace evaluation of various solutions, removing the possible two solution regions noted in Part 1 [Meinel and Meinel, Appl. Opt. 20, 3627 (1981)]. The study is extended to include one reflection plus one transmission aspheric and two reflection aspherics.
