Abstract: Aspects of the present disclosure include systems for irradiating particles in a flow stream. Systems according to certain embodiments include a light source having a first laser configured to irradiate a flow stream at a first position and a second laser configured to irradiate the flow stream at a second position and a light detection system having a single light collection component configured to collect light from the flow stream and a single photodetector array having a plurality of photodetectors configured to detect light from the lasers conveyed through the single light collection component. Methods for determining one or more parameters of a particle in a flow stream with the subject systems are also described. Non-transitory computer readable storage medium with instructions for practicing methods with the subject systems are also provided.

Abstract: Aspects of the present disclosure include methods for array binning data signals from a photodetector (e.g., in a flow cytometer). Methods according to certain embodiments include detecting light with a light detection system from a particle irradiated by a light source in a flow stream, generating data signals in a plurality of photodetector channels in response to the detected light and binning data signals from two or more different photodetector channels to generate combined spectral data signals. Light detection systems having a detector component and a modulator component configured to bin data signals from two or more different photodetector channels are described. Systems (e.g., particle analyzer) having a light source and a light detection system for practicing the subject methods are also described. Non-transitory computer readable storage medium is also provided.
