Abstract
A laser beam optical adjusting mechanism for a particle size distribution measuring apparatus includes a light source to provide a laser beam for irradiating a sample cell and an optical detector unit for receiving an intensity pattern representing the impact of the laser beam on a cell. A mirror assembly is positioned adjacent the light source to reflect the laser beam to irradiate the sample cell. An actuator unit is provided for adjusting the mirror assembly to line an optical axis of the light source with an optical detector. The actuator unit can be automatically driven by a controller and can be of a compact configuration by the use of a pair of lever members that are pivotally supported and respectively driven by actuators.
