Abstract

PURPOSE:To enable to measure accurate light flux diameter which gives effect to the beam operation, by measuring the diameter of light flux toward multi-direction of laser beam. CONSTITUTION:After the array 3 fitted to the support set 6 is placed on the reflection light part of scanning optical system, the fitting plate 4 is placed suitable 2 or 3 directions and the array output is measured through the emission with reflection beam, and if the center position of the array 3 is not opposed to the center of light flux, the center is correctly opposed with the adjustment of the adjusting screw and the micrometer. After that, the fitting plate 4 is sequentially set to the click direction and the diameter of light flux at each direction within 180 deg. is measured with the measurement of the output of the array 3.
