Abstract
A sample measurement device includes: a sample container that stores a sample solution; a light source that irradiates the sample container with irradiation light from a first direction; an imaging part that captures an image of the sample solution based on light scattered by the sample solution from a second direction intersecting the first direction; and a calculator that calculates an absorbance or a concentration of the sample solution based on the image. The calculator calculates a degree of attenuation of a light amount of the image at a constant optical path length along the first direction based on the image, and calculates the absorbance or concentration of the sample solution according to the degree of attenuation.
