Abstract

With the continuing trend to use very fast primary mirrors in telescopes, there will be a need for optical designs for magnifying correctors. Such correctors will serve to give an aberration-corrected field of view at a larger f-number and scale than for the primary mirror alone. One solution to this is to use a system with a small secondary mirror. The final focus is closer to the prime focus than the usual Cassegrain position. One form of this is described together with a new two-lens corrector.
