<p>A light amount is increased and an analyzing accuracy can be increased in accordance with an enlargement of a load angle.. However, scattered light tends to be loaded into a light receiving element in an analysis accompanied by scattered light, and the dynamic range of a concentration which can be measured becomes narrow. In the invention, light is dispersed by a light dispersing portion (20), a load angle of the received light is changed per wavelength, the load angle is made larger for light of a wavelength having a small light amount, and the load angle is made smaller for light of a wavelength having a large light amount and used for an analysis accompanied by scattered light. Accordingly, it is possible to gain a dynamic range of a concentration which can be measured in the analysis accompanied by scattered light, while increasing the light amount and maintaining the analyzing accuracy.</p> |
