ABSTRACT:
A laser diffraction particle size analyzer irradiates a laser beam on particles in a scattered state, and measures a spatial intensity distribution of diffracted and scattered light from the particles. A particle size distribution of the particles is calculated from a result of the measurement. The laser diffraction particle size analyzer includes a laser device for generating an ultraviolet laser beam as a light source for generating a laser beam, and a fluorescent member closely attached to or disposed adjacent to a detecting surface of a photodiode array that measures the spatial intensity distribution of the diffracted and scattered light upon incidence thereof.
