A pair of optical prisms arranged in a complementary relationship provides for anamorphic magnification and cooperates with a refractive or diffractive cylindrical lens element, the later of which generates an aberration that at least partially compensates an aberration generated by the pair of optical prisms. The refractive or diffractive cylindrical lens element is rotated out of normal with respect to the optic axis of the system so as to provide for reflecting stray light away from the optic axis.
