Barcode reader having multiple illumination systems and multiple sets of imaging optics

摘要

According to one aspect of the invention, there is provided a barcode reader, comprising a first illumination system that emits first illumination with a first illumination spectrum, and a second illumination system that emits second illumination with a second illumination spectrum. The second illumination spectrum is broader than the first illumination spectrum. The barcode reader also comprises a first lens assembly with a first optical path through the first lens assembly to a first image sensor section. The first optical path includes a first filter configured to pass an acceptance spectrum of electromagnetic radiation and attenuate an attenuated spectrum of electromagnetic radiation. The first illumination spectrum is primarily composed of the acceptance spectrum. The barcode reader also comprises a second lens assembly with second optical path through the second lens assembly to a second image sensor section.
