Abstract

An optical system includes lenses and a prism. The prism includes a first transmissive surface, a first reflective surface, a second reflective surface, and a second transmissive surface. A first rectangular region at a reduction conjugate point: has an imaging relationship in which the first rectangular region is conjugate to a second rectangular region at a magnification conjugate point; and does not intersect with an optical axis. When a space is divided into a first space and a second space, all principal rays passing through the first rectangular region pass through the first rectangular region, the first transmissive surface, and the first reflective surface in the first space, and pass through the second reflective surface and the second transmissive surface in the second space.
