Abstract
A rotating, draft angle polygon scanner system for correcting wobble by double reflection of an infinite conjugated light beam from a pair of fixed mirrors having optical power provided by aspheric surfaces. In addition to their wobble correction function, the optical powered mirrors provide the scan and focus functions of conventional f-.theta. scan lens optics and hence such f-.theta. scan lens optics can be eliminated from the scanner system, thereby providing an all mirror scanner system.
