Abstract
The invention relates to a capillary tube holder with a recess for holding a capillary tube. At least one pair of light channels is provided perpendicular to the axial direction of the recess. Each pair of light channels has an incoming light channel to supply light beams to the capillary tube and an outgoing light channel to transmit said light beams to an evaluation device. The light channels extend radially with respect to the recess and lead therein. Light conductors comprising individual fibres are provided in each incoming light channel and each outgoing light channel and are arranged upstream of the capillary tube. The diameter of each individual fibre corresponds at least approximately to the internal diameter of the capillary tube, and a plurality of individual fibres of the light conductors is arranged parallel and/or radially to the longitudinal axis of the capillary tube in the area where the light channels lead into the recess.
