Abstract: A flow cytometer includes a capillary having a sample channel; at least one vibration producing transducer coupled to the capillary, the at least one vibration producing transducer being configured to produce an acoustic signal inducing acoustic radiation pressure within the sample channel to acoustically concentrate particles flowing within a fluid sample stream in the sample channel; and an interrogation source having a violet laser and a blue laser, the violet and blue lasers being configured to interact with at least some of the acoustically concentrated particles to produce an output signal.

Abstract: The present set of embodiments relate to a system, method, and apparatus for an optical configuration in a flow cytometer that allows for independent adjustment of focusing for each light source. Such systems, methods, and apparatuses require a final focusing element to be moved near the beginning of the optical train and for each optical element coming after the final focusing element to be configured to accommodate converging light beams while minimizing the introduction of aberrations into those beams.
