Abstract:
1. A spectrometric analyzing device for analyzing a thin film on a supporting member that is optically transparent to incident light, the device comprising: a light source capable of emitting light to a measurement portion to be measured, at n different angles of incidence, θ a polarizing filter provided between the light source and the measurement portion and shielding an s-polarized component of the light emitted from the light source; a detection unit receiving transmitted light transmitted through the measurement portion, thereby detecting transmission spectra, S; a regression operation unit obtaining an in-plane mode spectrum, S where superscript, T, denotes a transposed matrix and superscript, −1, denotes an inverse matrix, the mixing ratio, R, is expressed by a matrix below: where C denotes a constant and θ an absorbance spectrum calculation unit calculating an in-plane mode absorbance spectrum, A
