Abstract
A system for identifying microorganisms and other microscopic particles in a fluid, includes a laser that directs a laser beam ( ) through a detect zone ( ) and a plurality of photodetectors ( ) that detect light scattered in different directions from a particle at the detect zone, and includes a carrier ( ) that confines fluid to movement along a narrow path. The carrier includes a glass sphere ( ) with a passage ( ) for carrying the fluid. The spherical surface allows light scattered at a large angle from the direction of the laser beam, to pass through the glass sphere to its outside for detection there.
