Abstract:
1. A lithographic apparatus, comprising: an illumination system configured to provide a beam of radiation; a support configured to support a patterning device, the patterning device configured to impart the beam with a pattern in its cross-section; a substrate table configured to hold a substrate; a projection system configured to project the patterned beam onto a target portion of the substrate; a plurality of EUV radiation sources configured to provide EUV radiation to the illumination system; and a distributor configured to convert the EUV radiation from each of the plurality of EUV sources into an intermediate beam of radiation, the intermediate beam of radiation being directed from the distributor in a first direction by a mirror surface, wherein the distributor comprises a rotationally driven mirror arrangement including an axis of rotation being non-parallel to the mirror surface, wherein the axis of rotation of the rotationally driven mirror arrangement substantially coincides with the first direction.
