Abstract
Systems and methods for analyzing particles flowing in a channel are described. In an embodiment, the channel is configured to flow a particle through a lumen of the channel, the channel defining an interrogation window configured to allow light to pass into and out of the lumen; a light engine comprising: a first light source positioned to output first excitation light onto a first portion of the channel in the interrogation window; and a second light source positioned to output second excitation light onto a second portion of the channel in the interrogation window separate from the first portion. In an embodiment, the systems include an emission fiber bundle comprising a first emission optical fiber and a second emission optical fiber, wherein a proximal end of first emission optical fiber and second emission optical fiber are arranged in an emission fiber bundle head.
