The device has a detector (2) with a detector unit, where a differential amplifier (24), which is downstream of the detector, has inputs (52, 53) and outputs (54, 55). The differential amplifier has negative feedback paths (56, 57), which extend from the outputs to the inputs. Another detector unit is provided in the negative feedback paths. The two inputs are connected with the two outputs by the two negative feed back paths, respectively. |
