Abstract
An apparatus for and a method of parallelizing the conjugate deflected light beams of a magneto-optic light deflector system. The apparatus includes two converging half-lenses, the centers of which are removed. The two converging half-lenses are oriented superposed with their centers aligned along the center of the light beam that is directed normally incident to the plane of the magneto-optic light deflector. A converging lens is oriented in the optic axes of the parallelized conjugate light beams for focusing the two parallelized conjugate light beams upon a screen or detector.
