Abstract:
An optical scanner assembly for exposing an image on photosensitive media positioned on the internal surface of a drum platen, the assembly comprising:a laser assembly for producing a laser beam representative of the image to be exposed on photosensitive media; a semi-circular flexible lens curved to the shape of the photosensitive media positioned on the internal surface of the drum platen, the lens being a plano-convex cylinder lens having a convex side facing said media; a laser beam scanner positioned between said laser assembly and said lens to scan said laser beam through the lens across the media in an image-wide pattern; and a baffle located out of the said laser beam path between said scanner and said lens for extinguishing laser beam reflections from said convex side of said lens; wherein said baffle has a semi-circular shape concentric with said flexible lens.
