Abstract:
A projection optical system ( 1 ) that projects from a first image plane on a reducing side to a second image plane on an enlargement side, including a first refractive optical system ( 11 ) that includes eight lenses (L 1 ) to (L 8 ) and forms a first intermediate image ( 31 ) on the enlargement side using light that is incident from the reducing side, a second refractive optical system ( 12 ) that includes six lenses (L 9 ) to (L 14 ) and forms the first intermediate image ( 31 ) on the reducing side into a second intermediate image ( 32 ) on the enlargement side, and a first reflective optical system ( 20 ) that includes a first reflective surface ( 21 a) with positive refractive power that is positioned closer to the enlargement side than the second intermediate image ( 32 ).

Claim (Index 3):
The projection optical system according to  claim 2 ,\n wherein a maximum effective diameter of the second refractive optical system is smaller than a maximum effective diameter of the first refractive optical system.
