ABSTRACT:
The present invention divides the light to be measured, which is incident to a photo-detector having a plurality of photo-cells from a light source through a specimen to be measured and through a dispersion element, into a wavelength of a high sensitivity region and a wavelength of a low sensitivity region, reads out the light of the high sensitivity wavelength region with a quicker period than the light of the low sensitivity wavelength region, and adds the signals thus read out for each wavelength region in order to obtain spectra for the full wavelength.
