Abstract
An apparatus and method for analyzing a fluid with particle analytes, where the fluid is fed through a passageway within an optical fiber and excitation light is guided by the optical fiber across the passageway and intersects the fluid therein. The optical core is made multimode and is adapted to shape the excitation light with a uniform spatial illumination over a cross-section of the optical core and the passageway is configured relative to the optical core such that the particle analytes are exposed to substantially equal excitation light while circulating in the passageway.
