Abstract

PURPOSE:To improve precision by eliminating the effect of temperature fluctuations of interference filters upon a measurement result, by irradiating all interference filters with light from a light source all the time and by guiding light passed through a specific filter to a sample. CONSTITUTION:Light guides 22 are provided as many as interference filters 24, which are irradiated with light from a light source 21 all the time. A rotary member 25 is turned under an interference filter holding member 23 fixed in position to guide light passed through a prescribed interference filter 24 to a prism 29 through a light guide 28, and the luminous flux is changed in direction to a prescribed phodometric position to irradiate a reaction pipe 35, containing a sample liquid 34, with the luminous flux; and the light passed through the reaction pipe 35 is photodetected by a photodetector 36 and converted photoelectrically to measure the light absorbance of the sample liquid 34. Each interference filter 24 never changes in characteristics at the beginning of photometric operation, so accurate data is obtained.
