The optical system includes a plurality of off-axis ellipsoidal mirrors (102) defining first and second focal points; the first focal point is coincident with a flow tube extending through the optical system. Multifunction optical units (103) are located at the second focal points of the ellipsoidal mirrors. High intensity excitation light impinges on the material flowing through the flow tube (101).

Why it's free to use
- Filed February 27, 2002 and granted September 13, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 27, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 27, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
