    摘要： A bar code reader indicator feature gives visible indication that a bar code function has been performed. The feature is integrally molded with the exit window to simplify the design and reduce cost. The feature can diffuse light from an existing indicator light within the reader or the scanning light beam can be directed to impinge upon an area of the exit window not normally in the beam path when the function has been performed to illuminate the feature.

    摘要： A wide angle, athermalized, achromatic, hybrid imaging lens assembly captures return light from a target over a field of view, and projects the captured return light onto an array of image sensors of a solid-state imager during electro-optical reading of the target. The assembly includes a plastic lens group for optical aberration compensation, a glass lens group spaced away from the plastic lens group along an optical axis, and an aperture stop between the lens groups and having an aperture through which the optical axis extends. The glass lens group has substantially all the optical power of the imaging lens assembly for thermal stability, and the plastic lens group has substantially no optical power. A holder holds the lenses and the aperture stop in front of the array.

    摘要： An imaging lens assembly focuses light from indicia in a working range of distances along an optical path onto a solid-state imager of an imaging reader. The lens assembly includes an axicon and an aperture stop that together are operative for extending the working range.

    摘要： An optical collector collects relatively more of the off-axis light directed to a detector, and collects relatively less of the on-axis light directed to the detector, in order to decrease the variation in the amplitude of the electrical signal generated by the detector over a scan of target such as a bar code symbol in order to improve the performance of a bar code symbol reader.

    摘要： A solid-state imager is mounted in a reader, such as a bi-optical, dual window, point-of-transaction workstation, for capturing light along an optical axis over a field of view from diverse targets useful for customer identification, customer payment validation, operator surveillance, and coded indicia. An optical converter is located within the housing, for optically modifying and asymmetrically magnifying the field of view along mutually orthogonal directions generally perpendicular to the optical axis, and for increasing resolution of the imager along one of these directions.
