A hologon scanner system in which a laser beam is scanned across a receptor surface with an essentially bow-free scan. A focusing lens comprised of symmetrical, nonanamorphic optical elements is positioned in the scanned beam between the hologon deflector and the image plane. The focusing lens is provided with barrel or pincushion distortion and is tilted with respect to the scanned beam and bends the beam to correct for the bow introduced by the hologon deflector.
