ABSTRACT:
An alignment mechanism is provided for adjusting the optical center line of scanning beams generated in a ROS system. The collimator lenses which collimates the output of a diode laser source are mounted within a lens barrel. The lens barrel is positioned so as to be biased against the sides of a housing in which the ROS components are located. The barrel has eccentric rings mounted along its circumference which, when rotated, inpart motion to the lens barrel so as to change the center line of the collimated beam output. This provides adjustment of the scan line center line at the image plane.
