Abstract: A system, an apparatus, and a method are provided for a modular flow cytometer with a compact size. In one embodiment, the modular flow cytometry system includes the following: a laser system for emitting laser beams; a flow cell assembly positioned to receive the laser beams at an interrogation region of a fluidics stream where fluoresced cells scatter the laser beams into fluorescent light; a fiber assembly positioned to collect the fluorescent light; and a grating system including a dispersive element and a receiver assembly, wherein the dispersive element is positioned to receive the fluorescent light from the fiber assembly and to direct spectrally dispersed light toward the receiver assembly.

Abstract: A system, method, and apparatus are provided for cytometry with dual laser beams. In one example, the method includes directing an incident light beam from a source to enter an optical waveplate; polarizing the incident light beam into a polarized light beam in response to the incident light beam entering through the optical waveplate; directing the polarized light beam to enter a birefringent crystal; separating the polarized light beam into an ordinary light beam and an extraordinary light beam in response to the polarized light beam entering the birefringent crystal; directing the ordinary light beam and the extraordinary light beam to enter a lens; focusing the ordinary light beam and the extraordinary light beam into dual light beams separated by a beam displacement; and coupling the dual light beams to form a sample region having substantially uniform light intensity to analyze moving particles in the particle analyzer.
