Patent ID: 7128473

Claim:
A device for optically coupling an arriving light beam with a further-transmitting light-guiding fiber, comprising: (a) a first and a second coupling body, each of said first and second coupling bodies having a centric lead-through for leading through the light beam; and (b) an intermediate coupling body positioned between said first and second coupling bodies and having a centric lead-through for leading through the light beam, wherein the intermediate coupling body is displaceably and lockably held in one plane within the first coupling body, and the second coupling body is mounted in a pivotally and axially displaceable movable manner in the intermediate coupling body, and wherein the first coupling body comprises a planar flange which runs perpendicular to the centric lead-through and is surrounded by a circumferential collar, the circumferential collar being passed through by at least one first adjustment screws and at least one first locking screw, which act on the intermediate coupling body.
