Abstract
A light source, a standing wave forming unit, a detector, and an absorbance calculating unit. The light source irradiates a sample with light. The standing wave forming unit forms, in the sample, an acoustic standing wave perpendicular to a surface of the sample. A node of the acoustic standing wave is positioned at a predetermined distance from the surface of the sample, the light from the light source entering the surface of the sample. The detector detects light emitted from the surface of the sample, and is disposed on the surface of the sample on a side where the light source is disposed. The absorbance calculating unit obtains absorbance.
