Abstract:
A system for aligning a first and a second component of an optical head, wherein the first component includes a lens and the second component includes a photodetector array, the system comprising:a rotational stage; a first mechanical path extending from a first side of the rotational stage to an end of the first mechanical path, the first mechanical path comprising a first X-translation stage and a first Y-translation stage; a first holding mechanism attached to the end of the first mechanical path for holding the first component of the optical head; a second mechanical path extending from a second side of the rotational stage to an end of the second mechanical path, the second mechanical path comprising a second X-translation stage and a second Y-translation stage, wherein the rotational stage may rotate the first mechanical path with respect to the second mechanical path; a second holding mechanism attached to the end of the second mechanical path for holding the second component of the optical head; a Z-translation stage positioned so as to alter the spacing between the first and second holding mechanisms in a Z direction, a first microscope for viewing the first and second components of the optical head in the Z direction; and a second microscope for viewing the first and second components of the optical head in a direction perpendicular to the Z direction.
