Abstract: An optical scan module, for example for an optical scanner, includes an integrally molded plastics material member which defines not only the laser focusing lens, but also the laser focusing aperture and the collection mirror. In addition, the molded member may act to house and to locate both a semiconductor laser and a photodetector, thereby ensuring easy and accurate placement of those elements within the scanning assembly. The optical assembly may be in modular form, mounted onto a common printed circuit board with a beam scanner.

Abstract: An optical scanner such as a bar code scanner includes a segmented mirror (14), the individual sections of which have different profiles (16,18,20). By directing the scanning laser beam across the mirror, a plurality of scan lines are created, at different distances from the scanner. This provides increased flexibility by extending the scanner's working range. In alternative embodiments, a collector mirror and/or a scanning mirror may be segmented. In addition, beam shaping may be provided by reflecting the beam from one or more aplanar surfaces.

Abstract: An optical scanner such as a bar code scanner includes a segmented fold mirror, the individual sections of which have different profiles. By directing the scanning laser beam across the fold mirror, plurality of scan lines are created, at different distances from the scanner. This provides increased flexibility by extending the scanner's working range. In alternative embodiments, a collector mirror and/or a scanning mirror may be segmented. In addition, beam shaping may be provided by reflecting the beam from one or more aplanar surfaces.
