Abstract
An optoelectronic device for detecting marks with defined contrast patterns includes a transmitter to emit polarized light beams, a receiver to receive light beams and having an output to produce receiving signals representing the received light beams, and a an evaluation unit to which the receiving signals are fed and in which the contrast pattern of a mark is detected with the aid of the receiving signals present at the receiver output. A thin-film polarization filter is arranged in front of the receiver to filter out a share of the received light beams specular reflected back by the mark.
