Abstract
A device for generating light pulses for characterization, standardization and/or calibration of photodetectors, preferably within a flow cytometer or microscope is disclosed. The device includes emission light sources which are driven with predetermined waveform to emit light pulses. A feedback mechanism based on the provision of separate, series-connected control light sources whose emission is detected by a feedback detector is included. The device may include one or more emission groups of circularly arranged, multi-color emission light sources. To provide different intensity levels, the emission light sources or emission groups can be coupled into a light guide with different efficiencies. Uses of the device and systems or kits including the device is also provided.
