Abstract
A barcode scan module having an optical lens system with a central bore, an outer collection lens section, an inner beam focusing lens section, and an illumination source mounted within the central bore to form an integrated assembly, such an assembly may also include a photodetector array with all these components integrally mounted on a printed circuit board. The scan module may also integrate one or more of the following components: power supply and control electronics for the illumination source; power supply and control electronics for the scan engine; power supply and control electronics for the photodetector; and signal processing and/or decoding electronics for processing and/or decoding the scanned barcode signal produced by the barcode scan module.
