Abstract:
An illumination optical apparatus illuminates an object with illumination light. The illumination optical apparatus includes an optical integrator arranged in an optical path of the illumination light; and a polarization modulating member which modulates a polarization of the illumination light, the polarization modulating member being made of an optical material with optical activity and being arranged in the optical path on an incidence side of the optical integrator such that a direction of an optic axis of the optical material is coincident with a direction of an optical axis of the illumination optical apparatus. The polarization modulating member has a thickness profile varying with respect to azimuthal positions about the optical axis.

Claim (Index 9):
The illumination optical apparatus according to  claim 1 , wherein the polarization modulating member generates an azimuthal polarization state in an annular region on a pupil plane about the optical axis.
