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.
