Abstract
A beam recombiner is used to parallelize two first order beams emanating from an magneto-optic stripe domain light deflector. One arrangement uses a concave cylindrical mirror with a negative meniscus lens attached thereon to redirect a conjugate beam. The other arrangement uses a concave cylindrical mirror with a cylindrical rod lens placed at the radius of curvature of the mirror to redirect the conjugate beam.
