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.
