Abstract

PURPOSE:To measure simultaneously substances having abosrption spectra respectively in the regions of ultraviolet ray and visible ray by composing a flux of light by coinciding the optical axes of ultraviolet ray shielded at a specific period by an optical chopper and visible ray by means of partially transmitting and reflecting mirror. CONSTITUTION:The light from a light source which radiate ultraviolet rays is shielded at specific period by an optical chopper 5 which rotates a disc by means of a servomotor 6 to be made into a parallel flux of light by a lens 4, and permitted to pass through a partially transmitting and partially reflecting mirror 8. On the other hand, the flux from a light source 1' which radiates visible rays is reflected at right angles by the mirror 8 to be coincides with the flux from the light source 1. The flux containing the ultraviolet ray and visible ray is bent by a full reflecting mirror 9 and is fed into an incidence window 11 of an absorption cell 10, then discharged out of the departure window 12. These parallel fluxes are introduced into a spectroscope 40 to be analyzed into spectrum. Then, the intensity of light delivered through outlet slits 55, 55' ... of this spectroscope 40 is converted into the strength of electric signal by the photoelectric transducer 8, and is processed in an electric processing system 100 having a switching circuit synchronized with the shielding period of the optical chopper 5.
