PURPOSE:To simplify a structure and to secure uniform result of analysis, by providing a spectrophotometer device for a plurality of channels, and performing measurement by a common light source and a common light detecting element. CONSTITUTION:Four parallel magnetic fluxes are obtained by a white-color light source 11. Only one parallel luminous flux is selectively passed by a luminous flux selector 14 at a certain time point, and guided to a sample cell 20 by way of a reflecting mirror 19-1. The direction of the parallel luminous flux, which has passed the sample cell 20, is changed by a reflecting mirror 19-2, and a focal point is formed on the surface of a concave mirror 21-2 by a concave mirror 21-1. The flux directly advances on a common light path from the surface of the concave mirror 21-2. Said parallel flux is divided by a spectroscope element 22 and reaches light detecting elements 23, where the wavelength and the signal are led out. |
