Methods and apparatuses for configuring radiation used in microlithographic processing of workpieces are disclosed herein. One particular embodiment of such a method comprises directing a radiation beam along a radiation path from a reticle to an adjustment structure. The radiation beam has a wavefront with a first configuration in an image plane generally transverse to the radiation path. The method continues by changing at least one independently controllable parameter of the adjustment structure to change the wavefront of the radiation beam from the first configuration to a second configuration. After changing the shape of the wavefront from the first configuration to the second configuration, the method continues by impinging the radiation beam on the workpiece.
