The principle of laser diffraction is the relationship that exists between light scattering (its angle and intensity) and particle size.. The larger the particle, the smaller the angle and the higher the intensity of the scattering.. This is made use of in every analyzer ever made, from the basic prototype to the latest LA-960 particle size analyzer..

Laser diffraction is grounded in the relationship between light and surfaces (in our case particles).. When light and surfaces interact, it results in either solely or a mix of refraction, reflection, absorption or diffraction.. The latter offers the greatest scope for accurate particle size analysis assuming the diffraction system contains the ..
Laser diffraction is one of the most common techniques for particle size analysis.. It is based on the observation that the angle of (laser) light diffracted by a particle corresponds to the size of the particle.. In a complex sample containing particles of different sizes, light diffraction results in a specific diffraction pattern..

Laser diffraction has become one of the most commonly used particle sizing methods, especially for particles in the range of 0..5 to 1000 microns.. It works on the principle that when a beam of light (a laser) is scattered by a group of particles, the angle of light scattering is inversely proportional to particle size (ie.. the smaller the ..
