Abstract: The device (V) serves the optical coupling of a light-beam (L) arriving from any optical component with a further-transmitting light-guiding fiber (F). It contains in each case an input-side and output-side coupling body (1,2) with in each case a centric lead-through (13, 22) for leading through the light (L) wherein in the device (V) there is arranged at least one lens (40) or a lens system. Between the input-side (1) and the output-side coupling body (2) there is arranged an intermediate coupling body (3) with a centric lead-Through (34), which in one of the input-side or output-side coupling bodies (1,2) is displaceably and lockably held in a plane, whilst the outer input-side or output-side coupling bodies (1,2) in the intermediate coupling body (3) is counted in an elastically (25) pivotally movable and axially displaceable manner. The device (V) permits a separate angular adjustment or parallel displacement of the input-side and output-side coupling bodies (1, 2) relative to one another.
