ABSTRACT:
A positioner for accurately and precisely positioning an optical member such as a lens aligned with the tip of an optical fiber in relation to an optical device such as a beam launcher/splitter; the positioner includes a tilt base mounted in a frame and angularly displaceable about orthagonal X and Y axes defined by three ball bearings all engaging one surface of the tilt base and all biased against the tilt base. Two differential screws mounted on the frame engage two of the ball bearings to effect angular yaw and pitch adjustments. The tilt base is connected to a retainer support in turn connected to a retainer member; two additional differential screws engage the support through further ball bearings to effect linear movements of the retainer member along the X and Y axes. The retainer member includes a lens and an adapter aligned along the Z axis with an optical fiber cable whose tip is releasably connected to the adapter; the adapter has an internal flange that accurately locates the tip of the optical fiber at the focal point of the lens.
