    摘要: A lithographic apparatus (2) can include a radiation source (SO) configured to provide radiation (200), a radiation collector (CO) configured to collect radiation (200) from the radiation source (SO), an illumination system (IL), and a detector (300). The detector (300) can be disposed in a fixed positional relationship with the illumination system (IL) relative to an alignment of the collector (CO). Further, a region (310) of the collector (CO) can be configured to direct a portion of radiation (200) emanating from the radiation source (SO) and traversing the region (310) towards the detector (300). The detector (300) can be configured to detect a change in a portion of the radiation (200). The change can be indicative of a change in position or orientation of the collector (CO) relative to the illumination system (IL) relative to an alignment of the collector (CO).

    摘要: An illumination system having a plurality of reflective elements, the reflective elements being movable between different orientations which direct radiation towards different locations in a pupil plane, thereby forming different illumination modes. Each reflective element is moveable to a first orientation in which it directs radiation to a location in an inner illumination location group, to a second orientation in which it directs radiation to a location in an intermediate illumination location group, and to a third orientation in which it directs radiation to a location in an outer illumination location group. The reflective elements are configured to be oriented to direct equal amounts of radiation towards the inner, intermediate and outer illumination location groups, and are configured to be oriented such that they can direct substantially no radiation into the outer illumination location group and direct substantially equal amounts of radiation towards the inner and intermediate illumination location groups.
