A particle analyzer that includes optical waveguides, a support, and a detector. The optical waveguides direct spatially separated beams from a source of radiation to produce measuring beams in a sample flow measuring area. The support maintains each of the optical waveguides in a fixed relative position with respect to each other and maintains the positioning of the measuring beams within the measuring area. The detector senses light produced from the measuring beams interacting with a particle flowing through the measuring area. At least one of the support and the detector can be coupled to the core stream sample system. The coupling can use an optical waveguide device configured to convey optical radiation arising from sample interaction to the detector. In another example, a particle analyzer comprises an optical system configured to be fixedly coupled to a sample system and configured to direct beams along independent beam paths from a source of radiation to produce measuring beam spots in a sample flow measuring area of the sample system and a detection system configured to sense radiation delivered from the sample flow measuring area.
