description An apparatus for controlling a depth of field for a reader in a vision system includes a dual aperture assembly having an inner region and an outer region. A first light source can be used to generate a light beam associated with the inner region and a second light source can be used to generate a light beam associated with the outer region. The depth of field of the reader can be controlled by selecting one of the first light source and second light source to illuminate an object to acquire an image of the object. The selection of the first light source or the second light source can be based on at least one parameter of the vision system.
