Abstract
Method and apparatus are disclosed for stabilizing an optical scanner having a rotational axis and a substrate with facets which are generally pyramidal, the outer diameter of the facets being proximate to a base plane which is generally perpendicular to the axis. The method includes adapting the scanner to reduce the inertial deformation of the facets during high speed rotation of the scanner by shaping the substrate beyond the base plane such that during rotation it is substantially inertially symmetric about the base plane.
