<p>PROBLEM TO BE SOLVED: To provide a measuring apparatus, for the reflection of light, by which information on a deep part inside an object to be inspected can be measured by using light in a wavelength region having a small penetration depth and by which a component in an organism such as fat, protein, sugar or the like absorbed in a wavelength region of 1000 to about 2500 nm is detected more precisely. SOLUTION: A measuring apparatus is provided with an irradiation part A in which reflected light from the irradiated part of a sample S is not made incident on a detector, in which only light radiated after it is passed through the inside of the sample S so as to be scattered is used as detecting light, in which a deep part can be measured, in which a component in an organism such as fat, protein, sugar or the like absorbed in a wavelength region of 1000 to about 2500 nm can be detected more precisely and in which the sample S is irradiated with light, a detection part B which detects light from the sample S and a light shielding part C which is installed between the irradiation part A and the detection part B. The light shielding part C shields reflected light which is directly incident on the detection part B from the surface of the sample S, and the detection part B detects only scattered light from the inside of the sample S radiated from the surface of the sample S on a side different from the irradiation part A with reference to the light shielding part C.</p> |
