Beschreibung
Zusammenfassung:	A collector transfers EUV illumination light from a radiation source region to illumination optics. Imaging optics of the collector image the radiation source region in a downstream focal region. The imaging optics are embodied so that the radiation source is imaged with at least one first imaging scale by the EUV illumination light, which is emitted with beam angles 70°. The two imaging scales for the beam angles 70° on the other hand differ by no more than a factor of 2.5. In addition to a corresponding collector, an illumination system contains field facets transfer optics.
