Abstract
An apparatus for the calibration of a sensor system has at least one sensor and at least one excitation source, a control device for controlling the sensor system, a calibration medium and a drive which moves the calibration medium into an optical path of the sensor system in a calibration mode and moves the calibration medium out of the optical path of the sensor system in an operating mode for the testing of measuring objects. The calibration medium has more than one reference, where the drive moves the calibration medium into the optical path of the sensor system so that one of the references covers a detection area of the sensor system, and the sensor system measures the reference located in the detection area.
