ABSTRACT:
A flow cytometry apparatus for determining characteristics of cells or the like flowing in a liquid stream includes a nozzle for generating a liquid flow path for moving cells therethrough substantially one at a time. A light source, such as a laser, provides a beam of illumination. At least one prism is interposed in the path of the incident beam of illumination for expanding the beam in at least one direction and for directing the expanded beam toward the cells in the flow path. A lens is provided to focus the expanded beam on the moving cells. An appropriate sensor detects light with respect to each moving cell for associating that detected light with a characteristic of such cell.
