Abstract

Beams from a laser 2 are imaged via a relay lens 4 and spot-forming optics 6 so as to form beam diameters of the correct size and location near a first cylinder lens 8 after reflection from a folding mirror 9, Cylinder lens 8 acts in the tangential direction (the scan direction) to converge the laser beam to an aerial focus so as to fill the full aperture of a prescan objective (achromatic doublet) lens 10. Operating on-axis, the prescan objective lens reimages the aerial image created by the cylinder lens S at the document plane 12, Located between the prescan objective
