TL;DR: In this paper, a narrow beam of monochromatic light is directed through an optical chamber to intersect a thin stream of small particles to be optically analyzed, causing the particles to emit fluorescent radiation in the presence of a significant particle characteristic.
Abstract: A narrow beam of monochromatic light is directed through an optical chamber to intersect a thin stream of small particles to be optically analyzed, causing the particles to emit fluorescent radiation in the presence of a significant particle characteristic to be detected. A spectral filtering element is positioned to intercept the fluorescent particle radiation and to pass only a selected wave length to a photoresponsive pick-up element for detection thereby.
