Laser granulometry

The basis of the method is based on the phenomenon of scattered light with the combination of three blue lasers, 405 nm wavelength each, projected through a particle flow in order to determine the size and distribution from the same. The equipment detects and measures the intensity of the radiation diffracted by the particles passing through the path of the light beam. The particles in general, diffracted incident laser radiation at specific angles depending on their size.
