Device for injecting light into an optical wave guide

Abstract

A device for injecting light into an optical wave guide is provided, via which a focused light beam is oriented by a manipulator. A simple and precise adjustment of maximum injection efficiency during the injection of light into optical wave guides is facilitated, by a manipulator, and the permanent fixing of the adjusted positions obtained during the adjustment of the injection. The device can include: a manipulator having an adjusting plate comprising an outer part, an inner part, and two spring arrangements which are positioned between the outer part and the inner part and can be adjusted independently of each other along two co-ordinate axes, each spring arrangement having a parallel spring arrangement guiding parallel to a certain direction, and a preliminary spring mounted in series; a fixing screw that can be introduced into the fixed housing part by an axial threaded borehole; and an axially elastic fixing disk. The inner part can be moved in the X direction and in the Y direction and comprises the optical system connected to the optical wave guide to be injected with light. The fixing disk can be pressed into the adjusting plate by the fixing screw screwed into the housing part, against the detachable housing part, in the direction of the passage of the beam, such that the adjusted position of the inner part is fixed.
