Summary:A beam-forming and illuminating system for a lithography system, such an EUV lithography system, includes an optical element and an adjusting device. The adjusting device is configured so that, during a heat-up phase of the beam-forming and illuminating system, the adjusting device measures a field position and/or a pupil position of the beam-forming and illuminating system and adjusts the orientation and/or position of the optical element based on the measured field position and/or pupil position to keep the optical element in a desired position.
