Abstract:
1. An imaging apparatus comprising: an imaging assembly including an imaging lens and an image sensor array, the imaging assembly defining a field of view, the image sensor array having a plurality a pixels, the plurality of pixels including color sensitive pixels having wavelength selective color filter elements; an illumination assembly that, during a frame exposure period of the imaging assembly simultaneously projects on a target light within the blue wavelength band, the green wavelength band and the red wavelength band; wherein the imaging lens is a two element glass imaging lens, the imaging lens having a first glass lens element and a second glass element; wherein the imaging apparatus captures a frame of image data representing light incident of the image sensor array during an exposure period; and wherein the imaging apparatus includes a pass band filter that selectively passes light within first second and third pass bands, the first pass band being defined in the blue wavelength band, the second pass band being defined in the green wavelength band, the third pass band being defined in the red wavelength band; wherein the imaging apparatus processes the frame of image data for attempting to decode decodable; and wherein the imaging lens has a chromatic aberration to effective focal length ratio of less than 0.025.
