Abstract:
A projection optical system ( 10 ) projects from a first image plane ( 5 ) on a reducing side to a second image plane ( 6 ) on an enlargement side. The projection optical system ( 10 ) includes a first optical system ( 11 ) that includes a plurality of lenses and forms a first intermediate image ( 51 ) formed inside the first optical system ( 11 ) by light incident from the reducing side into a second intermediate image ( 52 ) on the enlargement side of the first optical system ( 11 ); a second optical system ( 12 ) that includes a first reflective surface (M 1 ) with positive refractive power which is positioned further to the enlargement side than the second intermediate image ( 52 ); and a glass block ( 30 ) that is disposed between the first optical system ( 11 ) and the first reflective surface (M 1 ), the glass block ( 30 ) passing light rays from the first optical system ( 11 ) to the second intermediate image ( 52 ).

Claim (Index 3):
The projection optical system according to  claim 1 ,\n wherein an image height Ih of the first image plane and a radius Mr of the first reflective surface satisfy a following condition\n 1.0< Mr/Ih< 2.25.
