発明の名称 (英語) OPTICAL DEVICE AND ANALYSIS APPARATUS
発明の概要(英語) Proposed are an optical device and an analysis apparatus which are capable of reliably enhancing Raman scattered light from a sample by a surface plasmon and improving the sensitivity of surface enhanced Raman scattered light compared to conventional ones. In this optical device (5), a surface plasmon (P) can be excited on the proximity surface in proximity to a sample (S) of a metallic nanoparticle (9) by forming a flat surface in the metallic nanoparticle (9), thereby making it possible to reliably enhance Raman scattered light from the sample (S) by the surface plasmon (P) and improve the sensitivity of surface enhanced Raman scattered light (L3) compared to conventional ones. Further, the molecular structure in the depth direction (z) of the sample (S) can be measured with high depth resolution by providing the focus of excitation light (L1) in the vicinity of an interface between the metallic nanoparticle (9) and the sample (S) by an objective lens (4).
