Claim Text:
1. A lithographic apparatus comprising: a substrate holder constructed to support a substrate; a modulator configured to expose an exposure area of the substrate to a plurality of beams modulated according to a desired pattern; a projection system configured to project the modulated beams onto the substrate, the projection system comprising an array of lenses to receive the plurality of beams, the lenses arranged side by side and the projection system configured to move at least part of the array of lenses across an optical axis of the modulated beams; and a control system configured to cause the at least part of the array of lenses to move across the optical axis of the modulated beams, while radiation of at least one of the modulated beams passes through at least one of the lenses during exposure of the exposure area, to cause the at least one modulated beam to change positional orientation or displace.
