Abstract:
The present invention allows more freely setting of the polarization direction of illumination light on an illumination surface of an exposure device. A beam transmission system ( 121 ) that transmits, to an exposure device ( 130 ), a linearly polarized optical beam (L) output from a free electron laser device ( 10 ) includes: an optical beam splitting unit ( 50 ) configured to split the optical beam (L) into a first optical beam (L 1 ) and a second optical beam (L 2 ); and a first polarization direction rotating unit ( 51 ) configured to rotate the linear polarization direction of the first optical beam (L 1 ).

Claim (Index 15):
The illumination optical system according to  claim 12 , wherein the illumination surface is illuminated with both of the first optical beam via the first field facet mirror and the pupil facet mirror and the second optical beam via the second field facet mirror and the pupil facet mirror.
