Abstract
An optoelectronic sensor for the detection of objects in a monitored zone is provided that has a light transmitter for transmitting transmitted light of a wavelength range, a light receiver for generating a received signal from the transmitted light remitted at the objects, a reception optics arranged upstream of the light receiver and having an optical filter adapted to the wavelength range for the suppression of extraneous light that is arranged in the reception beam path where the remitted transmitted light forms parallel bundles of beams, and a control and evaluation unit that is configured to detect information on the objects from the received signal. The reception optics here is optimized for an annular image field having an image field angle α and the filter is optimized to a non-perpendicular angle of incidence of the remitted transmitted light corresponding to the image field angle α.
