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 4):
The projection optical system according to  claim 2 ,\n wherein an optical axis of the first refractive optical system and an optical axis of the second refractive optical system are common, and the second intermediate image is formed on an opposite side of the common optical axis to the first intermediate image.
