Measuring device for an optical medium.

摘要

The two transmitters (SE1, SE2), which are mounted fixed on the measuring device (MV) at a distance from one another, are assigned a single common receiver (E12). This common receiver (E12) is retained on the measuring device (MV) by means of a mechanical sliding guide (AR) in such a way that it can be optionally assigned spatially to either of the two transmitters (SE1, SE2).
