Abstract
The invention relates to a projection system for projecting one or more beams on a target, said system comprising a frame, a projection module comprising a beam source for providing the one or more beams, projection optics for projecting beams on the target, a target positioning module, comprising a carrier for carrying the target, a stage for carrying and positioning the carrier, a measurement system for determining a position of the projection module relative to the carrier, a controller adapted for controlling the target positioning module to position the target under the projection module based on said determined position, wherein the projection module is connected to the frame via a flexible coupling for dampening the propagation of vibrations from said frame to said projection module, and wherein the controller is adapted control the target positioning module to compensate for residual vibrations as measured by said measurement system.
