    Abstract: There is set forth herein an indicia reading terminal having an illumination subsystem for projection of an illumination pattern, the illumination subsystem having at least one light source, the illumination subsystem being switchable between a first state and a second state, wherein the illumination subsystem in the second state projects illumination light at a projection angle that is more narrow than a projection angle of illumination light projected by the illumination subsystem when the illumination subsystem is in the first state. An indicia reading terminal can include an imaging subsystem including an image sensor array and an imaging lens for focusing an image of a target onto the image sensor array, the imaging lens being a variable imaging lens and having a first lens setting at which the lens assembly has a relatively nearer plane of optimum focus and a second lens setting at which the imaging lens has a relatively farther plane of optimum focus setting.
