More Information
Summary:An optoelectronic sensor for detecting objects in a monitored zone is provided that has at least one light transmitter for transmitting a plurality of mutually separated light beams, a transmission optics for the transmitted light beams, at least one light receiver for generating a respective reception signal from light beams remitted by objects, a reception optics for the remitted light beams, and a control and evaluation unit for obtaining information on the objects from the reception signals, wherein the transmission optics and/or the reception optics has/have a first optical system. In this respect, the transmission optics and/or the reception optics has/have a second optical system for correcting aberrations comprising a plurality of optical correction elements that are each associated with a light beam and the second optical system is arranged between a beam separation plane.
