Abstract:
A method for measuring an angularly resolved intensity distribution in a reticle plane ( 24 ) of a projection exposure apparatus ( 10 ). The apparatus includes an illumination system ( 16 ), irradiating a reticle ( 22 ) arranged in the reticle plane ( 24 ) and having a first pupil plane ( 20 ). All planes of the projection exposure apparatus which are conjugate thereto are further pupil planes, and the reticle plane ( 24 ) and all planes which are conjugate thereto are field planes. The method includes: arranging a spatially resolving detection module ( 44 ) in the region of one of the field planes ( 24, 30 ) such that the detection module is at a smaller distance from this field plane than from the closest pupil plane ( 20 ), radiating electromagnetic radiation ( 21 ) onto an optical module ( 42 ) from the illumination system, and determining an angularly resolved intensity distribution of the radiation from a signal recorded by the detection module.

Claim (Index 1):
A projection exposure apparatus for microlithography comprising a radiation source for generating exposure radiation, and an illumination system disposed downstream of the radiation source and configured for radiating the exposure radiation into a reticle plane of the projection exposure apparatus, wherein the illumination system comprises:\n a beam expanding optical unit for expanding a beam cross section of the exposure radiation from the radiation source, a beam angle redistribution module for deflecting partial beams of the exposure radiation from the beam expanding optical unit, a divergence amplification module for amplifying a divergence of the beam from the beam expanding optical unit, and an exchanging device for exchanging at least one element of the beam angle redistribution module for the divergence amplification module.
