CRYSTALSIZER^® - description of functions

Unique measurement structure
The measuring principle of the Crystalsizer is based on the diffraction of incoherent "white" light in the particle flow. The light source consists of a halogen lamp whose light is modulated in a ring shape by means of a liquid crystal display (LCD).

The LCD generates light in the form of circular rings of different diameters. An LCD diameter results in a detector signal when particles of a certain matching size are in the sample. These particles then deflect the light to the detector at a suitable angle.

During the measurement, the individual rings of the Liquid Crystal Display are "run through" in fast succession until the whole sample has been processed and measured.

The innovative measuring principle means that the Crystalsizer combines the advantages of mechanical and optical measuring instruments so that it is capable of measuring even larger quantities of samples quickly, precisely and in full detail.
