Abstract

PURPOSE:To make it possible to adjust such that the difference in the light signals between two light sources may is reduced as much as possible thereby to make it feasible to use a light adjusting mechanism by adjusting the composing ratio of a light composer in accordance with the intensities of the two light sources. CONSTITUTION:The lights irradiated from light sources 1 and 2 are composed by a composer 3 to enter a spectroscope 5 so that the desired light emanating from the spectroscope 5 may be converted into electric signals by a detector 6. The lights from the two sources 1 and 2 are amplified so that the difference inbetween may be detected by a difference detector 9 to turn or slide the composer 3. Thus, it is possible to reduce the difference in the quantitiy between the two sources 1 and 2.
