Abstract:
A microlithography optical system includes a projection objective and an illumination system that includes a temperature compensated polarization-modulating optical element. The temperature compensated polarization-modulating optical element includes a first polarization-modulating optical element of optically active material, the first polarization-modulating optical element having a first specific rotation with a sign. The temperature compensated polarization-modulating optical element includes also includes a second polarization-modulating optical element of optically active material, the second polarization-modulating optical element having a second specific rotation with a sign opposite to the sign of the first specific rotation.

Claim (Index 8):
An exposure apparatus which exposes a substrate to light via an object having a pattern, the exposure apparatus comprising:\n a stage which holds the substrate, the illumination optical apparatus as defined in  claim 2  which illuminates the pattern with the light; and a projection optical system which projects an image of the pattern illuminated with the light onto the substrate held by the stage, wherein the polarization modulating member has a region without optical activity in an area perpendicular to the optical axis, the region being on the optical axis, and wherein the polarization modulating member has substantially constant thicknesses in at least two radial directions that are not parallel to each other.
