ABSTRACT:
A device is described for optically coupling a radiation source unit to at least one optical monomode transmission fiber. The fiber core has a tapered end portion by which it can be connected to a known radiation source housing without very stringent requirements on the positional accuracy of the fiber relative to the optical components in the housing.
