Abstract: An optoelectronic sensor (10) according to the principle of triangulation for detecting an object (36) in a monitoring region (18) comprises a light transmitter (12) and a spatially resolving light receiver (26). A receiving optics (22) and an optical element (24) are arranged in front of the light receiver (26), wherein the optical element (24) comprises a converging partial region (24a) and a diverging partial region (24c) and is arranged such that a remitted light bundle (20) from an object (36) in a near range of the monitoring region (18) passes through the converging partial region (24) and a remitted light bundle (20) from an object (36) in a far range of the monitoring region (18) passes through the diverging partial region (24c).
