A laser scanner for reading symbology, such as barcodes. The laser scanner includes a housing, a laser source or generator disposed in the housing and operative to generate a laser beam, and an output window supported by housing and being positioned to receive the laser beam incident thereon. The window is operative to transmit the laser beam therethrough at a symbology target. In one embodiment, the window includes a vertical wedge angle between front and rear surfaces of the window that is oriented substantially in alignment with a vertical axis defined by the window. The vertical wedge angle is preferably oriented perpendicular to a horizontally-extending scanning line of the laser beam on the window. In one embodiment, the vertical wedge angle is substantially the same along the entire length or width of the window.
