<p>PURPOSE:To reduce the number of working steps on a sample to the minimum possible by forming a total reflection surface at the tip of a conducting member while a light emitting element and a light receiving element are arranged at the rear end thereof. CONSTITUTION:Light from a light emitting element 5 is incident on a photoconductive material 1 from an incident surface and reflected in multiplicity to reach the tip end thereof. The light is totally reflected on a plane 8 at the front end of the photoconductive material and transmitted to the side of a light receiving element 7 through a photoconductive material body 2, emitted from an outgoing surface 4 to be incident on a spectroscope 10 and the outgoing light is incident on the light receiving element 7 to measure spectrum with a spectrum analyzer 6. Under such a condition, when a sample is brought into contact with the plane 8, light with a specified wavelength is absorbed by the sample thereby accomplishing measurement of an absorption spectrum of the sample.</p> |
