DEVICE FOR GENERATING LIGHT PULSES FOR CHARACTERIZATION, STANDARDIZATION OR CALIBRATION OF PHOTODETECTORS IN FLOW CYTOMETERS

摘要

A device for generating light pulses for characterization, standardization and/or calibration of photodetectors, preferably within a flow cytometer or microscope. To this end the device comprises emission light sources which are driven with predetermined waveform to emit light pulses. The device is characterized by a feedback mechanism based on the provision of separate, series-connected control light sources whose emission is detected by a feedback detector. 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.
