Abstract
An atomic absorption spectrophotometer that memorizes the maximum amount of light of each light source when an transmissivity of each of a plurality of dimmers is largest; computes an appropriate transmissivity of each dimmer for equalizing the amounts of light of the plurality of light sources from the maximum amount of light of each of the light sources; and sets the dimmer's transmissivity to be the appropriate transmissivity.
