ABSTRACT:
A sample cell for making light scattering measurements, incorporating an exterior surface acting as both a lateral and vertical lens, is described. This unique structure permits greatly improved measurement of the light scattered by molecules and particles suspended in a fluid contained therein or flowing therethrough while illuminated by a fine light beam incident thereon. The resultant lensed structure of the cell, when integrated into a scattered light photometer and combined with suitable apertures before each scattered light collecting detector, reduces significantly stray light from entering each such detector.
