LIGHT BARRIER AND METHOD FOR DETECTING OBJECTS

摘要

The invention relates to a light barrier comprising a semiconductor component (1) and to a method for detecting objects. Said component comprises a carrier (2), a semiconductor chip (4) that detects electromagnetic radiation, a semiconductor chip (3) that emits electromagnetic radiation and a direction-selective element (5, 8) that limits an angular spread of the radiation that can be received by the detector semiconductor chip (4) and/or of the radiation that can be emitted by the emitter semiconductor chip (3). A primary radiation axis (V) of the radiation that can be received is tilted in relation to a primary radiation axis (U) of the radiation that can be emitted.
