Abstract
A barcode reader comprises a first lens assembly with a first field of view and a first optical path for first illumination from the first field of view to project to a first image sensor section. The barcode reader further comprises a second lens assembly with a second field of view and a second optical path for second illumination from the second field of view to project to a second image sensor section. The barcode reader further comprises a first illumination system positioned outside of the first field of view projecting the first illumination into the first field of view at a first angle from the first optical path. The barcode reader further comprises a second illumination system positioned between the second lens assembly and a point from which the first illumination system projects the first illumination into the first field of view.
