    摘要: The invention concerns a method for operating a projection exposure apparatus to project the image of a structure of an object (5) arranged in an object plane (6) onto a substrate (10) arranged in an image plane (8). The object (5) is illuminated with light of an operating wavelength of the projection exposure apparatus according to one of several adjustable exposure modes. The light produces changes in at least one optical element (9) of the projection exposure apparatus, by which the optical properties of the projection exposure apparatus are influenced. The operation of the projection exposure apparatus makes allowance for the influencing of the optical properties of the projection exposure apparatus or a quantity dependent on the former, being calculated approximately on the basis of the exposure mode used and the structure of the object (5).

    摘要: The disclosure provides an illumination system of a microlithographic projection exposure apparatus, as well as related methods and components. In some embodiments, the illumination system includes an optical element configured so that, when a linearly polarized entry beam which has an angle spectrum is incident on the first optical element, a maximum aperture angle of the entry beam at the first optical element is not more than 35 mrad. A component, which is rotationally symmetric about an optical axis of the system, of a birefringence present in the illumination system can be at least partially compensated by the first optical element.
