Abstract
An imaging head (404) for writing an image on a substrate (108) includes an array of emitters (104) comprised of groups of emitters (120, 116, 112); imaging lens (408) that focuses light from each group onto the substrate; and wherein light from each group is focused at a different depth relative to a surface of the substrate.
Claims10
An imaging head for engraving an image on a substrate comprising:
- an array of emitters comprised of groups of emitters wherein focal points of all of said emitters are arranged on a line wherein said line is inclined relative to a Y direction wherein said Y direction is perpendicular to direction of drum rotation on surface of said substrate;
- an imaging lens configured to focus light from each group onto said substrate wherein said imaging lens is used to focus light emitted from all of said emitters;
- wherein by inclination of said line light from each group of emitters is focused at a different depth relative to a surface of said substrate;
- and
- wherein said imaging head is inclined at an angle relative to said substrate.
