An optical scanning device and method are provided for marking an
optically sensitive layer. The device can include an optical source
capable of emitting a beam. At least one pivot can be configured to
enable the beam to travel through a beam output arc. In addition, a
mirror surface can be oriented toward the optically sensitive layer. The
mirror surface can be configured to reflect the beam within the defined
beam output arc onto a plurality of locations of the optically sensitive
layer.
