The excitation light source (1) emits excitation light that advances in the optical medium (3) toward the sample (5) placed on the sample placement surface. The probe light source (2) emits probe light advancing in the optical medium (3). The light position detector (4) detects the position of the emitted probe light emitted from the optical medium (3). The arithmetic unit (11) calculates the position of the probe light emitted by the light position detector (4) when the sample (5) is a reference substance that absorbs the excitation light and does not have a specific absorption peak within the excitation wavelength of the excitation light, and the position of the probe light emitted by the light position detector (4) when the sample (5) is a biological substance. The amount or concentration of the biological component in the biological substance is calculated.
