Paper Abstract
In this paper we present optical designs for an entirely new approach to extremely large
telescopes and telescopes with spherical primary mirrors. The key feature is a novel
optical system referred to as the improved spherical aberration corrector (ISAC). This
corrector works exceptionally well for post prime focus applications, as well as for
Cassegrain and Couder/Schwarzschild-like optical systems with both spherical primary
and spherical secondary mirrors. The Couder/Schwarzschild configuration also adapts to
a pancake configuration where the telescope is physically shorter than its aperture.
