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 1):
A projection optical system that projects from a first image plane on a reducing side to a second image plane on an enlargement side, comprising:\n a first optical system that includes a plurality of lenses and forms a first intermediate image formed inside the first optical system by light incident from the reducing side into a second intermediate image on the enlargement side of the first optical system; a second optical system that includes a first reflective surface with positive refractive power which is positioned further to the enlargement side than the second intermediate image; and a glass block that is disposed between the first optical system and the first reflective surface, the glass block passing rays from the first optical system to the second intermediate image.
