Abstract
A device permitting multiple focusable fields of view, such as a universal bar code scanner that can read bar code symbols at both near and far distances for a range of X-dimensions, is described. The scanner uses an adjustable optical imaging system that has at least two different focused fields of view. In one embodiment, the optimal field of view for a target object can be automatically selected with the use of a range finder.
