ABSTRACT:
A scanner for the acquisition of optical information, in particular bar codes, is proposed, which has a laser device (3), a receiving device (23), which detects laser light (25) reflected from the surface, carrying the optical information, of the object (13), and a measuring device (27), which emits a control signal corresponding to the distance from the object (13). The scanner (1) is distinguished by the fact that the laser device (3) has a single laser light source (37), and that a focusing device (31) is provided which can receive the control signal of the measuring device (27) and enables the scanner (1) to be adapted to the distance from the object (13), on the surface of which the optical information or the bar code (15) is present.
