Abstract (en)

[origin: WO9847377A1] The invention concerns an optoelectronic device for image acquisition, in particular of code bars, comprising a housing containing an electronic scanning sensor (10), lighting means (26, 27), and optical means forming images on the sensor (10) and comprising a diaphragm (25). The invention is characterised in that the optical means include at least two diopter lenses (21, 40) arranged between the diaphragm (25) and the sensor (10), consisting of a symmetrical rotating lens (40) whereof the useful part is convex and of a cylindrical lens (21) not generating deviation in plane (X) parallel to the optical plane and convergent in plane (Y) perpendicular to plane (X).
