Filed: 1986-06-02
Abstract: PURPOSE:To reduce an illuminance irregularity of a light source position controller by directly monitoring the intensity distribution of an optical integrator of a secondary light source to symmetrically form the intensity distribution of the secondary source. CONSTITUTION:The light of an optical integrator of a secondary light source is reflected by a half mirror 2, and condensed through a condenser lens 3 on the surface of a mask 4. Luminous fluxes 8a, 8b passed through the mirror 2 are condensed by the lens 3 to pass a pinhole plate 6 having pinholes at a point conjugate with the center of the mask 4 to be incident on a photodetector 7. When matched to a lamp position, lamp is so regulated at its position that the luminous fluxes 8a, 8b symmetrical with respect to an optical axis become the same intensity at the lamp position while monitoring the output of the detector 7. Quadrant photodetectors are used as the photodetector, and the intensities of the lights incident to the dividing surfaces A and C, B and D are qualified so that the intensity distribution of the secondary source becomes symmetrical. Thus, the lamp as a light source can be accurately and easily positioned at the position where the illuminance distribution on the irradiated surface is symmetrical and not irregular.
