A bioptic barcode reader has a housing having a lower housing portion with an upper surface and an upper housing portion extending above the lower housing portion. A generally horizontal window is positioned at the upper surface and a generally upright window is positioned in the upper housing portion. An illumination assembly has an illumination field-of-view and an imaging assembly, including an image sensor, has an imaging field-of-view with a centerline that is directed at an angle relative to the upper surface. A mirror arrangement is configured to split the imaging field-of-view into first and second portions, redirect the first portion of the imaging field-of-view through the generally upright window, and redirect the second portion of the imaging field-of-view and the illumination field-of-view through the generally horizontal window such that the second portion is covered by the illumination field-of-view at the generally horizontal window.
