Machine vision devices with configurable illumination and aiming pattern generation are disclosed. An example system includes a housing having a cavity; an imaging sub-assembly mounted in the cavity including: an imager configured to capture an image; an aiming light source mounted in the housing configured to generate a collimated beam of light, an illumination light source configured to generate illumination light; and interchangeable first and second cover plates configured for mounting to the housing in front of the imaging sub-assembly to form an external cover for the housing and sealably protect the imager from an environment, wherein the first and second cover plates have respective passive optical elements that modify the collimated beam of light to form respective aiming patterns, and wherein at least one of the first cover plate or the second cover plate has a third optical element that modifies the illumination light.
