Abstract:
A projection optical system forms an intermediate image at a position conjugate to a reduction side imaging surface, and forms a final image conjugate to the intermediate image on a magnification side imaging surface. The projection optical system includes a convex mirror disposed to be closer to the magnification side than the intermediate image and at least one lens that has a positive or negative refractive power and is disposed in an optical path so as to be closer to the magnification side than the convex mirror.
