ABSTRACT:
An optical apparatus, for correcting deviations from straightness of an array of laser emitters in generally aligned positions along an array direction, includes a plurality of mirrors along the light beam paths and positioned to reflect its associated light beam along a folded light beam path. Individual mirrors are selectively displaced along its associated light beam path in a direction so as to align the reflected light beams from all of the plurality of mirrors along the folded light beam path, thereby to correct for any deviation of a laser emitter from the straight, array direction line of the laser emitters. According to a preferred embodiment, a plurality of lenslets having power in at least the array direction are positioned in the light beam paths between the laser emitters and the mirrors such that each lenslet receives the light from an associated laser emitter in the array. A cylinder lens in the light beam paths between the laser emitters and the plurality of lenslets have power in the cross-array direction reduce divergence of the beams in the cross-array direction. The cylinder lens produces a back focal plane of the beams; and a second cylinder lens with power in the cross-array direction collimates the beams after the beams pass through the back focal plane.
