A positioning device (500) for positioning workpieces along translations and through angular rotations about two or more axes of rotation. In particular, the positioning devices (500) can be employed in method for aligning an optical fiber (510) with an optical beam such that the axis of the optical fiber (510) is aligned coincident to the axis of the optical beam and the endface (508) of the optical fiber (510) is deployed at the global maximum along the axis of the optical beam. The positioning devices are for use laser-to-fiber set-ups, laser-to-spatial filter set-ups, fiber-to-fiber set-ups and the like.

[ What is claimed is:] [1.] A positioning device for positioning a workpiece, the positioning device comprising:(a) a base;(b) an intermediate member;(c) a first cross-shaped flexure connector including a pair of substantially perpendicular planar flexure members, the intersection between said flexure members defining a first axis of rotation, said base and said intermediate member deployed in a substantially diametrically opposed fashion about said first cross-shaped flexure connector so as to pivot said intermediate member relative to said base about said first axis of rotation;(d) a first actuator for providing angular rotation of said intermediate member relative to said base about said first axis of rotation;(e) a workpiece holder for holding the workpiece;(f) a second cross-shaped flexure connector including a pair of substantially perpendicular planar flexure members, the intersection between said flexure members defining a second axis of rotation, said workpiece holder and said intermediate member deployed in a substantially diametrically opposed fashion about said second cross-shaped flexure connector so as to pivot said workpiece holder relative to said intermediate member about said second axis of rotation; and(g) a second actuator for providing angular rotation of said workpiece holder relative to said intermediate member about said second axis of rotation.
