An imaging system includes a first imager, a second imager, and an aiming assembly. The aiming assembly is configured to selectively output light having at least one of a first pattern or a second pattern, where the light having the first pattern intersects a first imaging axis of the first imager and the light having the second pattern intersects a second imaging axis of the second imager. The aiming assembly defines a first light pathway that is common to the light for the first pattern and the second pattern and defines second and third light pathways. The light travels from the first light pathway along the second light pathway to selectively output the first pattern and travels from the first light pathway along the third light pathway to selectively output the second pattern.

Imaging system with aiming assembly configured to emit multiple light patterns

Concepts described in the present disclosure relate to imaging engines used in indicia readers, such as barcode readers. The imaging engine includes a printed circuit board, an imaging sensor, and imaging optics. Also, it includes an aiming assembly with an aiming illumination source and an aiming optics assembly. The assembly has an optic element holder and a first optical lens arrangement, where the optical holder includes at least one feature for active alignment in the XYZ direction. These arrangements produce different aim light patterns when projected on a surface.

Imaging engines for use with indicia readers and components thereof

A method and apparatus for capturing an image of at least one object appearing in a field of view (FOV). A housing has an image sensor an autofocusing lens assembly fixedly mounted relative thereto. The autofocusing lens assembly employs multiple lens groups and a liquid lens. The lens groups, liquid lens, and the image sensor are aligned such that light received within the FOV passes through the lens groups and liquid lens and impinges onto the image sensor. The image sensor generates an electrical signal indicative of the received image.

Optical arrangement for small size wide angle auto focus imaging lens for high resolution sensors

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.
