Flow cytometer and ultraviolet light disinfecting systems

摘要

An optical system including a unique mirror arrangement surrounding a tube containing a flowing fluid with suspended biological material can be configured as flow cytometer or as an ultraviolet light disinfecting system. The optical system includes a plurality of off-axis ellipsoidal mirrors defining first and second focal points; the first focal point is coincident with a flow tube extending through the optical system. Multifunction optical units are located at the second focal points of the ellipsoidal mirrors. High intensity excitation light impinges on the material flowing through the flow tube.
