Abstract
A structure for focusing, collimating or diverging the light beam from a solid state laser diode comprises means non-symmetrically mounted between the structure for holding the lens system and the means for holding the laser diode thereby to allow the laser diode to be adjusted in position relative to the lens system along the optical axis of the lens system. Surprisingly, the non-symmetrical mounting of the adjusting means relative to the optical axis of the lens system does not cause any substantial transverse movement of the laser diode relative to the optical axis of the lens system. In one embodiment, the adjusting means comprises a screw rotatably mounted such that one end of the screw is rotatably screwed into with the structure holding the lens system and the other end of the screw is in rotatable contact the structure holding the laser diode. This other end is adapted to receive a turning instrument thereby to allow the screw to be rotated to thus adjust the position of the laser diode relative to the lens.
