ABSTRACT:
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.
