<p>A system for identifying microorganisms and other microscopic particles in a fluid, includes a laser that directs a laser beam (14) through a detect zone (24) and a plurality of photodetectors (132) that detect light scattered in different directions from a particle at the detect zone, and includes a carrier (110) that confines fluid to movement along a narrow path. The carrier is glass and has a spherical outer surface (118) and a passage (116) for carrying the fluid. The spherical outer surface is approximately centered on the detect zone (124) and allows light scattered at a large angle from the direction of the laser beam, to pass through the glass to its outside for detection there.</p> |
