Abstract
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 (20) and a plurality of photodetectors (30) that detect light scattered in different directions from a particle at the detect zone. The system includes a glass carrier (110) that confines fluid to movement along a narrow passage (116) in the carrier. The front surface (130) of the passage is flat, to facilitate prediction of the scatter light paths, and to enable the passage to have a small cross-sectional area.
