    Abstract: 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.

    Abstract: An ultraviolet/visible/infrared spectrophotometer, with a pulsed light source (10), has a monochromator with variable slit width to provide variable spectral resolution. The dynamic range at the detectors (24, 28) is reduced by varying the pulse energy emitted by the light source (10) in accordance with the wavelength and slit width settings (34, 36), and/or by varying the slit height in accordance with the slit width. The ligth source (10) may be a xenon flash lamp.
