Abstract
In a colorimeter for use in a biochemistry field, an amount of transmitted light impinging upon a light receiving device is decreased corresponding to an absorbance of a reagent to be used by arranging a light adjusting device in the optical path. The amount of light transmitted through a blank cuvette is made substantially equal to an amount of light transmitted through the reagent. Therefore, even when the analysis is performed for an item using a high absorbance reagent, the deviation of the amount of transmitted light does not affect measured absorbance values, and thus it is possible to perform the color measurement in an accurate manner regardless of the reagent absorbance.
