A light barrier comprising a semiconductor component (1) and to a method for detecting objects with a carrier (2), a semiconductor chip (4) which detects an electromagnetic radiation, a semiconductor chip (4) which emits an electromagnetic radiation, and a direction-selective element (5, 8), which delimits an angle range of the radiation which can be received by the detecting semiconductor chip (4) and/or of the radiation to be emitted by the emitting semiconductor chip (3), wherein a main radiation axis (V) of the radiation which can be received is tilted relative to a main radiation axis (U) of the radiation to be emitted. |
