Abstract:
1. Calibration system for characterizing luminescence measurement systems, in particular spectrally resolving, wide-field and/or confocal imaging systems, comprising: (a) a baseplate having a thickness defined between a first side and a second side opposite to the first side, wherein the first side of the baseplate has at least one flow-through channel, wherein the at least one channel is formed as a sample chamber for the luminescence measurement system; (b) at least one reservoir in communication with the at least one channel and adapted to receive a liquid; and (c) at least one focusing device integrated into and located on the first side of the baseplate, the focusing device comprising a focusing surface adapted for setting a defined measurement beam focus of the luminescence measurement system to be calibrated, wherein the focusing surface is aligned with an interior space of the at least one flow-through channel, wherein the interior space of the at least one flow-through channel defines a plane extending longitudinally with respect to the baseplate, wherein the focusing surface is located in the plane defined by the interior space of the at least one flow-through channel, and wherein the at least one focusing device includes a highly planar lumenescing focusing surface comprising a wafer coated with a mono-layer of fluorescing nanoparticles or quantum dots.
