Abstract |
AB |
[EN] To provide a photoelectric sensor for detecting an object in a monitoring area.SOLUTION: A photoelectronic sensor includes: at least one light emitter (22) for delivering a plurality of light beams 26 that are separated from each other from one light emission point respectively; a light emission optical system (24) for the delivered light beam 26; at least one light receiver (32) for generating each light reception signal from each reflection light beam (28) reflected by an object and incident on each light reception point; a light reception optical system (30) for the reflection light beam (28); and an evaluation unit (40) for obtaining information on the object from the light reception signal. The light reception optical system (30) and/or the light emission optical system (24) are a dual-lens type objective lens for an annular image field of an image field angle &agr;. The objective lens includes a first lens and a second lens. The first lens is configured such that a light flux of any individual light emission point and/or light reception point having the image field angle &agr; hits on only a half of the second lens.SELECTED DRAWING: Figure 1 |
