The application of laser diffraction spectrometry to determine the size distributions of particles in the anomalous diffraction regime, i.e., particles with a refractive-index ratio close to one, has been examined. From a computer simulation, using the Mie theory and the geometrical optics approximation, it could be concluded that for suspensions with a refractive-index ratio near 1, the ...

Read MoreLow-power gas lasers are nearly ideal light sources for particle size spectrometers. Particle size spectrometers involving imaging and light scattering have proven most satisfactory and are described in detail. The imaging spectrometers use 2-5-mW He-Ne lasers and a photodiode array to size and provide particle shape information on particles 1-10,000 microns in diameter.
