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).

Abstract: A triangulation light sensor includes at least one light transmitter for transmitting a light signal into a detection zone, a light receiver having a plurality of receiver elements for receiving light from the detection zone reflected diffusely and/or specularly, and a reception optics arranged between the detection zone and the light receiver in the beam path, with the position of a light spot produced on the light receiver in a triangulation direction by the reflected light resulting in dependence on the distance of the object. The reception optics includes at least one multisegmented lens element having a plurality of lens segments with mutually spaced apart optical axes in the triangulation direction and at least one freeform lens element or one diffractive-optical element having a multisegmented lens element having a plurality of lens segments with optical axes spaced apart from one another in the triangulation direction.
