    Abstract: An imaging optical system has a plurality of mirrors, which image an object field (9) in an object plane (11) into an image field (13) in an image plane (14). A reflection face of at least one of the mirrors is configured as a free form face which cannot be described by a rotationally symmetrical function. The object field has an aspect ratio (x/y), which is greater than 1, a ratio of a minimal and a maximal transverse dimension of the object field being smaller than 0.9. In a further aspect, the object field (9) and/or the image field (13) deviate from a mirror-symmetrical field form. An illumination optical system (10) for illuminating the object field (9) has components guiding illumination light (3) which are designed to illuminate a correspondingly formed object field (9). The result is an imaging optical system, an illumination optical system and a projection exposure system equipped therewith, with which increased demands on the correction of imaging errors are taken into account over the field imaged by the imaging optical system.

    Abstract: A projection objective of a microlithographic projection exposure apparatus comprises a wavefront correction device (42) comprising a refractive optical element (44; 44a, 44b) that has two opposite optical surfaces (46, 48), through which projection light passes, and a circumferential rim surface (50) extending between the two optical surfaces (46, 48). A first and a second optical system (OS1, OS2) are configured to direct first and second heating light (HL1, HL2) to different portions of the rim surface (50) such that at least a portion of the first and second heating light enters the refractive optical element (44; 44a, 44b). A temperature distribution caused by a partial absorption of the heating light (HL1, HL2) results in a refractive index distribution inside the refractive optical element (44; 44a, 44b) that corrects a wavefront error. At least the first optical system (OS1) comprises a focusing optical element (55) that focuses the first heating light in a focal area (56) such that the first heating light emerging from the focal area (56) impinges on the rim surface (50).
