title: Optimum solution for spherical primary mirror with two and three aspheric corrector plates located near focus. Part 2.
abstract: 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.
