Indicia reading terminal including focus element with expanded range of focus distances
Embodiments of the present invention comprise an indicia reading terminal including a focus element that extends the range of focus distances at which the indicia reading terminal can decode decodable indicia. In one embodiment, the focus element comprises a variable form element and a variable position element, the combination of which causes an image distance that can change in accordance with a separation distance between these two elements. The focus element can comprise an actuator, e.g., a piezoelectric actuator, which can be coupled to the variable position element in a manner that can cause the variable position element to deform the variable form element, and in one example, the deformation changes the focal length of the variable form element.
