Optical sensor element for a measuring machine, and coupling element therefor on the measuring machine side

摘要

The invention relates to an optical sensor element for a measuring machine, comprising a coupling element (3) on the sensor element side for mechanically and optically connecting to a coupling element (18) on the measuring machine side. An optical fiber (22) is arranged in the coupling element (3) on the sensor element side, wherein said optical fiber comprises an optical interface (30) for connecting to an optical machine contact element (34) of the measuring machine, wherein said optical interface is formed by an optical sensor contact element (33) having a self-centering ferrule (23) that encloses the end of the optical fiber (22). The ferrule (23) is supported in the coupling element (3) on the sensor element side in a floating manner.
