ABSTRACT:
A reflecting imaging optical apparatus comprises a reflecting spherical optical system including a first spherical reflecting optical system and a second spherical reflecting optical system, and a spherical reflecting mirror disposed near the position of an intermediate image formed by the reflecting spherical optical system. The first and second spherical reflecting optical systems form concentric optical systems, respectively.
