Abstract
A remarkable set of designs is found when considering imaging between the vertices of two equi-curvature mirrors. An infinite number of solutions exist for different numbers of reflections in a multi-pass configuration. A surprising closed-form expression is obtained that provides the necessary mirror spacings for any number of reflections. Then, the aberration makeup of these systems is analyzed. It is found that all primary aberrations except for distortion can be fully corrected.
