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： An imaging optical system has a plurality of mirrors, which image an object field in an object plane into an image field in an image plane. 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 greater than 1. A ratio of a minimal and a maximal transverse dimension of the object field can be less than 0.9.

摘要： An imaging optics has a plurality of mirrors which image an object field in an object plane in an image field in an image plane. A pupil plane is arranged in the imaging beam path between the object field and the image field. A stop is arranged in the pupil plane. The pupil plane is tilted at an angle (α) with respect to the object plane, where α is greater than 0.1°. The imaging optics results allows for a manageable combination of small imaging errors, manageable production and good throughput.
