Abstract: An apparatus (10) for deflecting and for widening a visible range of a camera (24) is provided, wherein the apparatus (10) has a first mirror element (12) which is tilted with respect to the optical axis of the camera (24) in a longitudinal direction in order to supply light to the camera (24) from a visible range lying laterally with respect to the optical axis. In this connection the first mirror element (12) is additionally tilted in a transverse direction perpendicular to the longitudinal direction and the apparatus has a second mirror element (14) besides the first mirror element (12) which is tilted in the longitudinal direction and in the transverse direction with respect to the first mirror element (12).

Abstract: A polygon scanner (10) for detecting objects (24) in a monitored zone (22) is provided having a light transmitter (12); having a light receiver (30); having an evaluation unit (32); and having a rotatable mirror unit (20) for a periodic deflection of the light beam (16) that has a plurality of mirror facets (34) in order thus to scan an angular section multiple times per rotation of the mirror unit (20) by a respective mirror facet (34), wherein at least some of the mirror facets (34) have a different curvature from one another. In this respect, at least one of the mirror facets (34) is configured as a free-form surface whose curvature is adapted to the angle of incidence of the transmitted light beam (16) on the mirror facet (34) that varies during the rotation of the mirror unit (20).

Abstract: An optoelectronic sensor (10) has a light receiver (16) for converting received light from a detection area (12) into an electrical signal. The sensor (10) comprises an evaluation unit (18) for obtaining information about objects in the detection area (12) from the electrical signal and aiming means (22) having at least one light source (24) and a pattern generating element (28) to make the detection area (12) visible with a light pattern (36). The pattern generating element (28) comprises a plurality of cylindrical lenses (30, 32, 34) so that the generated light pattern (36) comprises a plurality of lines (38) showing the position of the detection area (12).
