    Abstract: An illuminator includes: a body with an opening, for receiving optical means; illuminating means arranged around the opening in a frontal face of this body and commandable to illuminate a space in front of the frontal face, electronic control means of the illuminator; heat dissipating means; connecting means for removably fixing the illuminator at least to the optical apparatus. The body of the illuminator includes a rear face opposite the frontal face which includes a plurality of distinct functional case elements positioned around the opening for receiving at least the electronic control means and/or which defines the heat dissipating means and/or the connecting means, in such a manner as to enable an operator, when the optical apparatus is associated with the illuminator, to access the optical means to dismantle the optical means from the apparatus and/or adjust optical adjusting means of the optical means.

    Abstract: Passive autofocusing is used in image acquisition devices (e.g., machine-readable symbol readers, cameras), and can be employed with shutter and/or event-based image sensors. An aimer pointer is easily detected in images, and one or more characteristics characterized at various focus positions of the optics. A size of a characteristic dimension and/or shape of the aimer pointer and/or a measure of sharpness of the aimer pointer is used to determine which image, and hence focus position, results in an optimized or even optimum (i.e., best) focus. The image acquisition system is then configured accordingly. Measuring aimer pointer size is typically less computationally intensive than conventional approaches. Use of a laser beam to produce the aimer pointer usually requires lower exposure time than other approaches. Image data can advantageously be windowed using a relatively small region of interest (ROI) based on a known aimer pointer position.

    Abstract: A camera device for an optical imaging system, such as a scanner system for imaging machine-readable indicia may include at least one printed circuit board (PCB), an image sensor, and a first lens device. The PCB(s) may define a recessed area having a mounting surface therein. The image sensor may be disposed within the recessed area and may be coupled to the mounting surface of the PCB. The first lens device may be coupled to the PCB(s) and may extend into the recessed area. The first lens device may be disposed in optical alignment with the image sensor. A second lens device, which may be adjustable (e.g., adjustable focal length), may be disposed between the first lens device and image sensor. The second lens may be positioned in the recessed area and/or coupled to the first lens device.

    Abstract: A photoelectric sensor includes an emitter that emits a plurality of light beams. Fractions thereof pass through transparent portions of a first body and a second body in series before intersecting an optically powered surface, which directs the fractions to a target focusing an image that passes through a perimeter of the first body in one direction and focusing an image that passes through a perimeter of the second body in a perpendicular direction. The emitter, first and second bodies, and the optically powered surface are positioned so as to form a light spot on the target within which the fractions of the plurality of light beams substantially overlap. The fractions of the plurality of light beams reflect off of the target and are received by a receiver, which detects changes in the light to determine whether a mark is present on the target.
