Abstract

Optical sensor system on a device for the treatment of liquids with at least one device for the projecting of light in the direction of an optical axis onto at least one illumination area in the space, an adjustment device for the adjustment of the relative position of the at least one illumination area and a boundary surface in a direction diagonal to the optical axis, an adjustment device for the adjustment of the relative position of the at least one illumination area and the boundary surface in the direction of the optical axis, a control device for controlling the adjustment devices, such that they simultaneously adjust the relative position of the at least one illumination area and the boundary surface diagonal to the at least one device for the imaging of the at least one illumination area during the adjustment of the relative position onto at least one photodetector and an evaluation device connected with the at least one photodetector for the evaluation of the at least one measurement signal.
