ABSTRACT:
A high-performance and low-cost image-forming optical system with a reduced number of constituent optical elements that is made compact and thin by folding an optical path using reflecting surfaces arranged to minimize the number of reflections. The image-forming optical system has a first prism and a second prism between a stop and an image plane. The first prism includes an entrance surface, a first reflecting surface, a second reflecting surface, and an exit surface. The first reflecting surface and the exit surface are the identical surface. The second prism includes an entrance surface, a first reflecting surface, a second reflecting surface, and an exit surface. In the second prism, the second reflecting surface and the entrance surface are the identical surface.
