ABSTRACT:
A photometric device comprises a photometric optical system for obtaining light outputs each having a predetermined wavelength by transmitting light from a light source to a sample to be measured through different light paths each having a filter, a detector for converting each light output into an electric signal, a switch for deriving first electric signals for one predetermined wavelength and second electric signals for another predetermined wavelength from the output signals of the detector, and a signal treating circuit for treating the first and the second electric signals to obtain a light absorption amount of the sample.
