Abstract: A barcode reader assembly for capturing at least one object appearing in a field of view (FOV) is provided that includes a reader enclosure, a circuit board to capture and decode the image, an imaging system, a sound generator housing, and a sound generator. The reader enclosure has an internal cavity in which the circuit board is disposed. The sound generator housing is operably coupled with the circuit board and includes at least one wall having at least one sound port and extending upwardly from the circuit board to form a sound chamber. The sound generator is operably coupled with the circuit board and is at least partially disposed within the sound chamber to generate a sound at a resonant frequency. The sound generator housing is dimensioned to amplify the resonant frequency of the sound generator and port the generated sound to the internal cavity of the reader enclosure.

Abstract: An optical assembly for an autofocus lens system for imaging an object appearing in an imaging field of view (FOV) is provided. The optical assembly includes a compensator lens assembly disposed along an optical axis, with the compensator lens assembly configured to receive light along the optical axis and to provide tuning of a flange focal length of the optical assembly. A variable focus assembly, including a variable focus optical element, is disposed along the optical axis to receive light from the compensator lens assembly. The variable focus optical element has a tunable focal plane. A fixed focus optical group is disposed along the optical axis to receive light from the variable focus assembly, the fixed focus optical group is configured to focus the light at the flange focal length of the optical assembly.

Abstract: A barcode reader, an imaging engine, and an optical assembly and method for assembling such to maintain stability through physical shock and to control decentration are disclosed herein. An example optical assembly includes an actuator, adjustable lens group, and rear lens group. The actuator includes an inner carriage, wherein one or more inner walls of the inner carriage are at least partially threaded. The adjustable lens group includes a first lens element, wherein the first lens element is threaded and held in place by the at least partially threaded one or more inner walls of the inner carriage, and a second lens element, wherein the second lens element is coupled to the first lens element, and further wherein the second lens element is fixedly co-located to the first lens element. The front lens group is actively aligned to the rear lens group, which includes one or more fixed optical elements.
