ABSTRACT:
An optical apparatus for correcting deviations from straightness of an array of laser emitters includes an array of laser emitters in generally aligned positions along an array direction. The positions of the emitters deviating from a straight, array direction line in a cross-array direction perpendicular to the array direction by a generally simple bend. Each laser emitter produces a beam of light in a direction normal to the array and the cross-array directions such that the light beams travel along individual light beam paths. A corrector device in the light beam paths aligns the light beam paths in a cross-array direction, thereby correcting for any deviation of the laser emitters from the straight, array direction line of the laser emitters. The corrector device includes a flexible fiber lens formed in a predetermined shape corresponding to the simple bend positions of the emitters, and a mechanical mount to which the lens is attached and which is flexibly adjustable to thereby effect forming the lens into the predetermined shape.
