Abstract
An optoelectronic sensor is provided that has at least one light transmitter for transmitting a plurality of mutually separated light beams starting from a respective one transmission point; a transmission optics for the transmitted light beams; at least one light receiver for generating a respective received signal from the remitted light beams reflected from the objects and incident at a respective reception point; a reception optics for the remitted light beams; and an evaluation unit for acquiring information on the objects from the received signals. The reception optics and/or the transmission optics is/are a two-lens objective for an annular image field with an image field angle that has a first lens and a second lens, with the first lens being configured such that bundles of rays of every single transmission point and/or reception point with an image field angle α only impinge on half of the second lens.
