Abstract
A system and method for performing flow cytometry is disclosed wherein the alignment of the light source with respect to the sensing region of the fluid stream is continuously controlled using a feedback control loop. An imaging apparatus is provided that images the system along the optical axis, between the field stop and the sensing region. In an embodiment, the cytometer includes a field stop having an H-shaped aperture and light diverters over the ends of the aperture that divert a portion of the light to peripheral detectors.
