Claim 12:
13. A method of assembling a machine vision device, the method comprising:
providing an assembly including:
a housing having a cavity;
an imaging sub-assembly in the cavity;
an aiming light source in the cavity configured to generate a beam of light, wherein the aiming light source is offset from the imaging sub-assembly; and
an illumination light source;

configuring the imaging sub-assembly to capture an image of a portion of an environment in an imaging field of view (FOV);
configuring the illumination light source to generate illumination light; and
selecting one of interchangeable first and second cover plates based at least on the configured imaging FOV; and
mounting the selected one of the interchangeable first and second cover plates to the housing to form an external cover for the housing and sealably protect the imaging sub-assembly from an environment,
wherein the first and second cover plates have respective first and second passive optical elements that modify the beam of light to form respective first and second aiming patterns, and
wherein at least one of the first cover plate or the second cover plate has an optical element that modifies the illumination light.
