ABSTRACT:
The device and the method are used for optical detection of at least one phase transition between at least two media, which are taken into a line and/or dispensed from the line by an intake and/or dispensing device. A light-emitting transmitter emits light across and onto the line at a measurement point provided for this purpose. A receiver receives the emitted light, which is influenced by media in the line, to form reception signals. At least one waveguide, which is arranged up to the measurement point on the probe, is provided between the transmitter and/or the receiver and the measurement point (M). Due to the fact that the waveguide is arranged in parallel to the line at least in the area near the probe and at least one deflection lens is provided in the area of the measurement point to deflect the light emitted and/or the light to be detected, a phase boundary or state can be detected, and the dead volume is reduced.
