IMPROVED OPTICAL FEATURES OF FLOW CYTOMETRY APPARATUS ABSTRACT OF THE DISCLOSURE A flow cytometry apparatus includes a trans- parent liquid flow chamber and a nozzle for providing a stream of particles, to be analyzed, through the flow chamber. A light source is provided along with a lens for focusing the light from the source at a region within the flow chamber through which the particles pass and for collecting light associated with those particles. Photoreceptors and the like are provided for detecting one or more characteris- tics of the particles related to light which strikes the particles. A spring or like biasing member provides and maintains stability between the lens and the flow chamber to particularly stabilize the relative axial position of the flow chamber and the lens.
