Abstract
A Raman spectroscopic device includes an optical resonator, in which a first reflecting body that exhibits semi transmissivity/semi reflectivity and has a surface which is a light scattering surface that generates Raman scattering, a transparent body, and a second reflecting body that exhibits reflectivity, are laminated in sequence one on another. The Raman spectroscopic device utilizes light absorption due to resonance to obtain a surface amplified Raman effect.

1-12. (canceled)
A Raman spectroscopic device for use in Raman spectroscopy, in which a measuring light beam of a particular wavelength is irradiated onto a sample in contact with a light scattering surface, Raman scattered light generated at the light scattering surface is spectrally decomposed, and is employed for detecting a detection target substance in the sample, in the form of an optical resonator, comprising:
- a first reflecting body that exhibits semi transmissivity/semi reflectivity and has a surface which is the light scattering surface for generating Raman scattering;
- a transparent body;
- and
- a second reflecting body that exhibits reflectivity, laminated in sequence one on another;
- whereby the intensity of the Raman scattered light is amplified by the amplified electric field at the light scattering surface by light absorption, generated by resonance in the optical resonator upon irradiation of the measuring light beam.
