Abstract:
1. A Raman light measuring apparatus for molecular measurement, comprising: an optical sensor including: each of the nano-columns includes a combination of a transparent portion and a noble metal portion having an anisotropic shape according to a shape of each nano-column and being formed at least on top of or in an intermediate portion of each of the nano-columns; and the large number of nano-columns are aligned so that their longitudinal direction of cross section taken substantially parallel to the substrate are substantially straight or substantially parallel; and a light irradiator configured to irradiate a linearly polarized laser perpendicularly to a surface of the optical sensor; a transmitted light monitor configured to measure an intensity of a transmitted light which has passed through the optical sensor; and a rotation controller configured to rotate the optical sensor in a plane which is perpendicular to an irradiated light so that the intensity of the transmitted light measured by the transmitted light monitor is minimized.
