ABSTRACT:
A spectrophotometer which takes out monochromatic lights from lights from light sources by using spectroscopes and transmits the monochromatic lights through a sample and detects the transmitted lights by sensors includes a plurality of dispersing elements in the spectroscope which bear the dispersion of different wavelength ranges or a plurality of sensors which bear the detection of different wavelength ranges in order to widen a measurement wavelength range; and means for correcting the difference between measured values obtained when the different dispersing elements were used or the difference between measured values obtained when the different sensors were used at one wavelength in overlap wavelength regions between different wavelength ranges so as to be set to zero.
