The invention relates to a calibration device (10) for characterizing luminescence measuring systems, in particular spectrally resolving, wide field and / or confocal imaging systems (a) a base plate (12) having at least one through-flow channel (18), wherein the at least one channel (18) is designed as a sample chamber for the luminescence measuring systems, (B) in each case at least one, with the at least one channel (18) communicating reservoir (20) for receiving a liquid and (c) at least one focusing device (24) integrated in the base plate (12) for setting a defined measuring beam focus of the luminescence measuring system to be calibrated with a focusing surface (26), which is preferably aligned with an interior of the at least one channel (18). |
