Abstract
A dataform reading module includes a 2D photosensor array, a first optic for focusing a first image representing a target dataform onto a first portion of the array, and a second optic for focusing a second image representing the target dataform on a second portion of the array. Preferably, the first portion and the second portion each have a width which is substantially equal to a width of the photosensor array. The first optic has a first best focus length and the second optic has a second best focus length which is different from the first best focus length. The module further includes an illumination device, such as a laser, for illuminating the target dataform.
