Abstract
An optical assembly for use in focusing a laser beam along an optical path onto a scanned surface. The optical assembly includes a first cylinder lens having a longitudinal axis and a transverse axis, located along the optical path for shaping and focusing the laser beam in a first direction, wherein the transverse axis is substantially perpendicular to the optical path. A second cylinder lens is provided having a longitudinal axis and a transverse axis, located along the optical path for shaping and focusing the laser beam in a second direction, wherein the transverse axis is substantially perpendicular to the optical path. The second cylinder lens longitudinal axis is not perpendicular to the optical path.
