Modulated light manner of light equipment and light equipment

摘要

Light equipment 3, lamp 23 and beam limiting device 25 and the suffering inspection body image pickup doing, on the basis of the luminosity target signal CS which generates on the basis of the luminosity of the image which can, CPU41a and the mode Change-over Switch 22a which change with CPU41c and the illumination mode which make the adjustment of the radiation light intensity of illumination light beam limiting device run 25 are possessed. CPU41c, after change to another side is specified from one side of the illumination mode which corresponds to illumination mode and the special optical observation mode which usually correspond to optical observation mode with mode Change-over Switch 22a, until the change with CPU41a completes, when change is specified, between, on the basis of the amendment value DA amendment present diaphragm value DC specified coefficient , with , adjustment of the radiation light intensity of illumination light is made to run to beam limiting device 25.
