A particle size analyzer for the determination of size of individual particles in the micron size range. The system for effecting the analysis comprises a laser 11 and means 12 for collimating the laser beam, a rotating wedge prism 14 for converting this beam to a circular rotation beam, focusing means 15 for focusing the beam to a fine point, a transparent carrier 17 for supporting the particles to be analyzed, and a photosensitive cell located behind the particle carrier. The laser beam interacts with the particles and the resulting signals, from each such interaction, are analyzed to provide information on particle size. The preferred analysis is based on the time of transition theory. The carrier is capable of being moved in the X-Y directions so that the entire area of the carrier may be analysed. <IMAGE> |
