Paper Abstract

An instrument is described for measuring both particle and droplet size distributions. Based on Fraunhofer diffraction of laser light, the measurement is fast, reliable, and easy to make. Hardcopy results include a characteristic diameter, distribution width, and a 15-segment histogram of the size distribution. Following a brief review of sizing techniques and the importance of measuring size distributions, a technical discussion is presented on the principles of the instrument. Configuration of the instrument is discussed. Five examples of commercial application are presented covering spray and particle samples.
