摘要: A particle counter (200) for optically detecting an unconstrained suspended in a flowing liquid includes: sample chamber (240) having fluid inlet and outlet; laser module (201) producing beam (212) ; shaping optical system (228) providing multiple pattern the chamber; CMOS detector located to detect light scattered by particles chamber, electric signal characteristic of parameter particle. The has sensing area within which intensity is at least 10 Watts/mm2 0.5 square mm or more. thirty more array elements. reflects refocuses effect passes same through area.
