Abstract: A measurement system that can measure scattered light across a predetermined scatter angle is disclosed. The measurement system has a light source (10) configured to provide light along a first axis. The measurement system has a lens system (3, 4) aligned along a second axis that has a first focus near the first axis and where the second axis is different than the first axis. The measurement system has a sensor (5) located on the second axis at a second focus of the lens system (3, 4) and is configured to detect scattered light near the first focus. The measurement system has a mask (9) located on the second axis and is configured to limit the light that reaches the sensor (5) to a predetermined angle of scatter. The disclosed invention eliminates the need for multiple nephelometric measuring devices and also system verification devices in order to perform assay of the presents or absence or number of suspended particles in a media as well as verification of the systems ability to measure in compliance to required performance attributes.

Abstract: A phase shift measurement system (100) comprises an excitation system (101), a luminescent material (103), and a detection system (102). The excitation system (101) transfers an excitation light wave (112). The luminescent material (103) transfers a luminescent light wave (113) in response to the excitation light wave (112). The detection system (102) detects the luminescent light wave (113) and generates a corresponding luminescent signal (114). The detection system (102) processes the corresponding luminescent signal with DFT logic (108) to determine a phase shift between the excitation light wave (112) and the luminescent light wave (113).
