    Abstract: There is disclosed an illuminator and collector apparatus and method for fluorescence analysis wherein illumination of a stream of particles produces fluorescent light. A reflector, having a concave reflector surface with a first focus disposed in the stream of particles, has reflected therefrom organized illuminating radiation, such radiation converging upon the first focus to stimulate the particles into producing the fluorescent light. The fluorescent light emanates from the first focus, a portion of which is reflected from the concave reflector surface. This fluorescent light which is focused on the second focus contains no (or negligible) amount of illuminating radiation and is collected for subsequent detection and processing.
