A portable data collection device including an imaging assembly including a two dimensional (2D) photosensor array. The imaging assembly is selectively actuatable with a first trigger for reading a target dataform in the imaging assembly's target area and actuatable with a second trigger for capturing a image of the target object in the target area. The device also includes an illumination assembly including an circuit board assembly supporting illumination and targeting light emitting diodes and a lens array or panel positioned adjacent the circuit board assembly for focusing an even pattern of illumination on the target area and generating a crosshair illumination pattern for aiming the device at the target dataform. The device further includes an optic assembly for focusing reflected illumination from the target area onto the two dimensional photosensor array. The optic assembly includes a focusing optic for changing a best focus distance of the optic assembly as a function of moving a wedge shaped optic with respect to a stationary optic to change a thickness of the focusing optic.

A portable data collection device comprising:a) a camera assembly, including an array of photosensor elements generating a signal representative of an image of a target area, the image including a dataform positioned in the target area; and b) an optic assembly positioned to focus illumination re
1. A portable data collection device comprising:a) a camera assembly, including an array of photosensor elements generating a signal representative of an image of a target area, the image including a dataform positioned in the target area; and b) an optic assembly positioned to focus illumination reflected from a generally rectangular target area onto the array of photosensor elements, the optic assembly including a focusing optic through which reflected illumination from the target area passes, the focusing optic including a movable lens movable along a path of travel transverse to a central ray of the reflected illumination passing through the optic assembly, movement of the movable lens changing a best focus distance of the optic assembly wherein the best focus distance corresponds to a distance between the device and the dataform which results in a clear image of the dataform being focused onto the array of photosensor elements.
