Abstract :
A scattering measurement system to determine the optical characteristics of industrial suspensions in the wavelength range 430-700 nm was realized. The suspensions were mixtures of water and solid matter; the optical characteristics measured were the absorption coefficient, the scattering coefficient and the anisotropy. The measurement system comprised two integrating spheres of 203 mm diameter, a light source and a multichannel optical power meter. Different lasers and a halogen lamp were used as light sources. Optical power was measured with a spectrophotometer or a conventional power meter.
