Abstract
A spectrophotometric analyzer disclosed by this invention has two monochromators capable of operating independently of each other. In each monochromator, a light beam from a light source is made to be incident on an entrance slit, and, after dispersed and wavelength scanned, issued from an exit slit as an analyzed light beam. These analyzed light beams are detected by detectors. The entrance slits and the exit slits of the two monochromators are disposed rotation symmetrically. This can simplify the operation of switching between a series mode where the analyzed light from the exit slit of the one monochromator is made to be incident on the entrance slit of the other monochromator and a parallel mode where the both monochromators operate for detection independently from each other.
