ABSTRACT:
The invention relates to a method and apparatus for conducting light onto cuvettes in a photometer. Onto each cuvette in a row, there is successively conducted light through a moving light-cutting disc (8), which is provided with a slot (10) at each light path. Thus the light passing through the adjacent cuvette does not disturb the measurement.
