    • A projection exposure system (10) for microlithography which includes: a mask holding device (14) holding a mask (18) with mask structures (20) disposed on the mask, a substrate holding device (36) holding a substrate (30), projection optics (26) imaging the mask structures (20) onto the substrate (30) during an exposure process, and a measurement structure (48) disposed in a defined position with respect to a reference element (16) of the projection exposure system (10), which defined position is mechanically uncoupled from the position of the mask holding device (14). The projection exposure system (10) also includes a detector (52) arranged to record an image of the measurement structure (48) imaged by the projection optics (26). The projection exposure system (10) is configured such that during operation of the projection exposure system (10) the imaging of the mask structures (20) and the imaging of the measurement structure (48) take place at the same time by the projection optics (26. An evaluation device (54) is configured to establish a lateral position of the image of the measurement structure (48) in the area of the detector (52) during the exposure process.

    • An illumination mask (10a) for a device for the range-resolved determination of scattered light, having one or more scattered-light measuring structures (11a) which respectively include an inner dark-field zone which defines a minimum scattering range, to an associated image-field mask and a corresponding device is provided. Also provided is an associated operating method and a microlithography projection-exposure system having such a device. The scattered-lighter measuring structure in the illumination mask has a scattered-light marker zone (20a) in the form of a bright-field zone, which on the one hand borders the inner dark-field zone and on the other hand borders an outer dark-field zone, which defines a maximum scattering range. The device may optionally be designed for the multi-channel measuring of scattered light by using a suitable image-field mask and also for multi-channel wavefront measurement, and the detection part may contain an immersion medium. Applications include, for example, the range-resolved determination of scattered light of projection objectives in microlithography projection-exposure systems.
