Abstract
Apparatus for measuring light scattering of a sample comprising a light beam source, means for collimating the beam and making it impinge on the sample in a perpendicular direction, at least one light sensor, and at least one spatial filter between the sample and the optical sensor, provided with two apertures, means for measuring the total power reaching the sensor and means for measuring the power of beams with a low k vector after the beam traverses the filter. The invention provides thus a simplified, portable and compact device for measuring different parameters like haze, turbidity, etc. can be built, for any sample and without the need of changing detectors.
