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 5):
The projection exposure apparatus according to  claim 1 ,\n wherein the divergence amplification module comprises two microlens element arrays having different focal lengths.
