Abstract
A correction element assembly for correcting misalignment of a beam of radiation with respect to a location on a target, includes a housing having a correction element fixedly mounted therein. A flexure is attached to the housing and at least two drive devices are disposed radially around the housing. Each of the drive devices is operable to apply a force to the housing to thereby deflect the flexure causing the housing to move such that said correction element moves in a cyclic fashion about its beam axis.
