ABSTRACT:
The eccentricity of the core of the light guide fiber relative to the outer casing of the light guide end portion is detected by viewing the end face while simultaneously rotating the light guide end portion. When an eccentricity is detected, the light guide fiber is displaced by impressing an impressing segment into the end face of the light guide end portion until the core of the light guide fiber extends coaxially with respect to the central axis of the light guide end portion. For that purpose the light guide end portion is clamped in an adjusting device under a microscope.
