IMPROVED PARTICLE SIZE ANALYZER

摘要

The present invention relates to a device for measuring the intensity of light scattered by a thin film of a colloidal medium, comprising: a monochromatic light source; a convergent optical system focusing said light source onto the thin film to be analyzed and comprising a dioptric element (7), one of the faces of which constitutes a first wall delimiting the thin film; at least one photosensitive detector reacting to the light scattered or backscattered by the thin film; and means for processing the signal coming from the photodetector. According to the device, the other, second wall is formed by a plane surface (3) on the end of a rod (2).
