ABSTRACT:
Apparatus for holding an optical fiber, having both longitudinal and radial adjustment capabilities. The fiber is disposed in a tubular member having an end disc which secures one end of the fiber in an eccentric hole therein. The tubular member is disposed in an eccentric hole of a threaded collet. Relative rotation of the collet with respect to the end disc provides for radial adjustment of the end of the optical fiber. Axial motion of the tubular member within the collet provides for longitudinal adjustment of the fiber. A tapered nut provides for locking capability of the tubular member with respect to the collet. A particular embodiment of the present invention provides a means by which the optical fiber may be adjusted with respect to an optical system to allow optical energy to be focused on the end of the fiber.
