摘要： An apparatus is described for the adjustment of the focal position of an opto-electronic apparatus including a transmitter element which transmits light and a lens for the focusing of the light transmitted by the transmitter element. The apparatus includes a pivotal lever for receiving the transmitter element or the lens, which is pivotable via a positioning element about a pivot joint for the adjustment of the spacing between the transmitter element and the lens and thus for the adjustment of the focal position. The pivotal lever is formed as a two-armed pivotal lever, with the one arm of the pivotal lever being formed to receive the lens or the transmitter element, and with the positioning element acting on a section of the other arm of the pivotal lever lying on the other side of the pivot joint. Furthermore, a variant is described in which the positioning element extends along the longitudinal extent of the pivotal lever, as well as an opto-electronic apparatus with such an adjustment device.

摘要： An optoelectronic sensor has a light source (10) for the transmission of a scanning beam (11), a light deflection unit (12), which is formed for the periodic deflection of the scanning beam (11) within an angular transmitting range (14), a receiving device for detection light reflected from an object to be sensed and/or back-scattered light, and a deflector (18) which has a light entry surface (20) arranged at least regionally within the angular transmission range (14). The light deflector is formed for the deflection of light incident through the light entry surface (20) onto a photo-detector (22). The photo-detector (22) can be coupled to a synchronization circuit to produce a synchronization pulse for the determination of the start of a sensing period.
