Abstract

The invention is directed to a device for calibrating an optical detection channel for a two-dimensional, spatially dependent measurement of fluorescent or luminescent radiation in multi-specimen carriers. The invention provides a system for calibrating an optical detection channel for a two-dimensional, spatially dependent measurement of fluorescent or luminescent radiation in multi-specimen carriers permitting a highly accurate calibration of the spatial sensitivity distribution of the sensor array in the detection channel. The invention provides a plate-shaped housing, a luminescent foil inside the housing which is arranged parallel to the window so as to cover its surface, a power source and control units which are provided in the housing for controlling the luminescent foil, so that the luminescent foil can be controlled for homogeneous emission of luminescent light through the window of the housing in different intensity levels.
