A compensator for manipulating a radiation beam traveling along an optical path. The compensator includes a fixed support holding a first optical wedge and an adjustable support holding a second optical wedge. The adjustable support includes a base, a stage holding the second optical wedge, first and second flexures, and a drive block. The stage defines a cavity and is movable relative to the base and the fixed support. The first and second flexures couple the stage to the base such that the stage translates along a stage path. The drive block is disposed in the cavity of the stage and is configured to translate along a drive block path perpendicular to the optical path and perpendicular to the stage path. The drive block includes first and second drive bearing surfaces configured to translate the stage in first and second stage directions, respectively, along the stage path.
