Abstract:
A projection optical system consists of, in order from the magnification side, a first optical system, which consists of one convex mirror and a plurality of lenses disposed on the reduction side of the convex mirror, and a second optical system. The lens closest to the magnification side in the first optical system is a negative lens. Assuming that a paraxial radius of curvature of the convex mirror is Mr and a focal length of the negative lens closest to the magnification side in the first optical system is fL1, Conditional Expression is satisfied: 0< Mr/fL 1<4.5.

Claim (Index 11):
The projection optical system according to  claim 5 , wherein Conditional Expression (4-1) is satisfied,\n \u22127< fA/|f|<\u2212 2.4\u2003\u2003(4-1).
