ABSTRACT:
An optical scanning system reduces wobble at the ends of the scan line by twice reflecting a laser beam off a facet of a rotating polygon mirror, then passing the beam through a cylindrical scan lens system which will focus the beam in the scan plane to the scan line and then reflecting the beam off a cylindrical mirror to focus the beam in the cross-scan plane to the scan line.
