    摘要: Imaging optics includes a first mirror in the imaging beam path after the object field, a last mirror in the imaging beam path before the image field, and a fourth to last mirror in the imaging beam path before the image field. In an unfolded imaging beam path between the object plane and the image plane, an impingement point of the chief ray on a used region of each of the plurality of mirrors has a mirror spacing from the image plane. The mirror spacing of the first mirror is greater than the mirror spacing of the last mirror. The mirror spacing of the fourth to last mirror is greater than the mirror spacing of the first mirror. Chief rays that emanate from points of the object field that are spaced apart from another have a mutually diverging beam course, giving a negative back focus of the entrance pupil.

    摘要: The disclosure relates an illumination system configured to guide illumination light from a radiation source to an object plane and to provide defined illumination of an object field in the object plane, wherein illumination light is supplied to the object field by a bundle-guiding optical pupil component which is disposed in a pupil plane of the projection objective, and wherein at least another bundle-guiding component is disposed upstream of the pupil component in the beam path of the illumination light. The disclosure further concerns a projection exposure apparatus that includes such an illumination system of this type, a method of fabricating a microstructured component using such a projection exposure apparatus, and a microstructured component fabricated using such a method.
