Abstract
The present invention provides a calibration device for an optical detector comprising a light emitting diode, and an electronic circuitfor driving the light emitting diode, wherein the electronic circuitis a constant current generator configured to supply a constant driving current to the light emitting diodein the range of 0.5 to 25 μA. Furthermore, the present invention provides a setting device for setting at least one calibration point for a calibration device as described above. The setting device comprises a light detectorconfigured to output a signal representing the light emission intensity of a calibration device under examination, a controllerfor controlling the constant driving current of the calibration device under examination, and a calibration point setting meansfor setting at least one calibration point for the calibration device under examination.
