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 20):
An exposure device including an illumination optical system, the exposure device comprising:\n a first field facet mirror and a second field facet mirror; a pupil facet mirror configured to reflect light via the two field facet mirrors; and a control unit configured to independently control a polarization direction of light incident on the first field facet mirror and a polarization direction of light incident on the second field facet mirror.
