Laser Light Scattering Particle Size AnalysisMeasuring Particles Ranging from Hundreds of Nanometers up to Several Millimeters in Size! During laser light scattering (also known as laser diffraction, laser diffractometry, Fraunhofer diffraction or Mie scattering), a laser beam passes through a dispersed particulate sample, large particles scatter light at small angles relative to the laser beam and small particles scatter light at large angles. Particle size is then determined from the measured variation in the intensity of scattered light as a function of scattering angle, using the Mie theory of light scattering. When compared to dynamic light scattering (DLS), Particle motion is less important since scattered intensity vs. angle is a direct function of particle size. Laser Light Scattering Particle Size Analysis is ideal for characterization of Particle size distributions from nanometers to millimeters.
