Abstract
There is described a laser scanning indicia reading terminal comprising a variable setting imaging lens having a first setting at which the terminal has a first plane of optimum focus and a second setting at which the terminal has a second plane of optimum focus. According to one embodiment a first predetermined scanning width can be associated to the first lens setting and a second scanning width can be associated to the second lens setting such that the terminal with the lens setting set to the first setting scans to a first width and with the lens setting set to a second setting scans to a second width. In addition to or in place of the scan width operational parameters different operational parameters can be associated to the respective first and second lens settings.
