ABSTRACT:
An optical scanner assembly for exposing an image on a scanned surface. The optical scanner assembly includes a laser mechanism for producing a laser beam representative of the image to be exposed on the scanned surface. The laser beam defines an optical path between the laser mechanism and the scanned surface. A laser beam shaping system is positioned along the optical path for focusing and shaping the laser beam onto the scanned surface. A scanning and directing system is provided for directing the laser beam to the scanned surface and scanning the laser beam across the scanned surface in an image-wise pattern. A unibody attenuation mechanism is positioned along the optical path for power attenuation of the laser beam, wherein the unibody variable density power attenuation mechanism is a linear density wedge.
