LASER MARKER SYSTEM

摘要

A laser marker system for marking indicia onto a substrate (146) includes an exit lens (140) having a focal length and a single laser source (120). The surface of the substrate (146) to be marked is positioned generally at the focal plane of the lens (140). The single laser source (120) is arranged so that its energy output beams are oriented in a generally parallel relationship. The single laser source includes segmented reflecting means (131) for generating a plurality of output energy beams (139) to create a column of spots on the substrate (146) with a higher resolution. The segmented reflecting means (131) is comprised of a back-reflecting mirror which is formed of a plurality of different mirror segments (131a-131n). A device is provided for moving each of the plurality of different mirror segments between a lasing position (148) and a non-lasing position (150) to vary the number of output energy beams and thus the number of spots on the substrate (146).
