ABSTRACT:
A particle analyzing apparatus is provided with applying means for applying a light beam to a particle to be examined, correcting means for multiplying the intensities of a plurality of components of scattered lights emitted from said particle to be examined which differ in scattering angle by a correction coefficient and adding them together, and operation means for calculating the particle diameter of said particle to be examined from the output value of said correcting means.
