Abstract
A method and apparatus for improving the image quality obtained by an imaging-based scanner comprising a housing supporting one or more protective windows. The apparatus further comprises at least one scanning arrangement, the scanning arrangement comprising illumination and imaging optics. The illumination and imaging optics form a respective field of view for imaging a target object. A light baffle is attached to the scanning arrangement. The light baffle has an aperture corresponding to each of the illumination and imaging optics such that stray light reflected from the protective windows is absorbed by the light baffle, improving the image quality of the imaging-based scanner.
