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.

Abstract: A laser diode module as an example has a laser diode pressed into a first housing part and a lens of an optical collimation system pressed into a cup-shaped second housing part. The second housing part is pressed into a cylindrical opening of the first housing part. In the opening there are molded three runners, which extend in the axial direction and are uniformly distributed in the peripheral direction, with the runners engaging on the jacket surface of the second housing part. The runners and the jacket surface form connection elements which are press-fitted together and which enable, apart from the connection, an adjustment of the lens relative to the laser diode. Pressure die cast zinc is in particular suitable as the material for the connection elements. An adhesive bond is not required with a holder of this kind.
