Abstract
In order for a parallel light beam to enable formation of an image at the center of a photodetectorwithout the use of an actuator for the adjustment by an order of micrometers, a particle size distribution measuring apparatusis provided with: a control unitfor calculating the distribution of particle size; a lenswhich is located between a light source unitand a cell baseand has an entrance planeand an exit planethat is not parallel to the entrance plane; and a lens drive mechanismthat can rotate the lensfor adjusting the optical axis so that the angle at which the parallel light beam enters into the entrance planecan be changed, wherein a detecting surfacefor adjusting the optical axis is formed on a photodetector
