Abstract
An optoelectronic device for acquisition of images, such as images of bar codes, includes a case which contains an electronic scanning sensor, an illumination source and optics including a diaphragm that permit the formation of images on the sensor. The optics include at least two diopters disposed between the diaphragm and the sensor. For example, the diopters may take the form of a revolved symmetrical lens, the useful part of which is convex, and a cylindrical lens which does not create any deflection in a plane parallel to the optical plane, and is convergent in a plane perpendicular to the parallel plane.
