Abstract
A lens is mounted on a pair of parallel flexures so that it is rigidly constrained in every degree of freedom except axial movement. To achieve micro adjustments, the flexures are moved by a compound screw having two sections of different pitch to effect movement of the lens at a rate dependent on the pitch difference.
