Abstract: A spectroscopic analysis device includes a light source configured to emit light including a plurality of wavelength components, a polarizer configured to convert the light emitted from the light source to a light of linearly polarized light to be radiated to a sample, a polarizing diffraction element configured to diffract and spectrally disperse a first polarization component included in the light having passed through the sample in a first direction, the polarizing diffraction element being configured to diffract and spectrally disperse a second polarization component included in the light in a second direction different from the first direction, a prism which is disposed on an exit side of the polarizing diffraction element and which has a first exit surface crossing the first direction and a second exit surface crossing the second direction, and in which angles of the first exit surface and the second exit surface with respect to a reference plane including the first direction and the second direction are different, an imaging element configured to capture an image of the first polarization component emitted from the first exit surface of the prism and an image of the second polarization component emitted from the second exit surface, and a processor configured to analyze the sample based on an imaging result of the imaging element.

Abstract: A spectroscopic analysis device includes: a light source configured to emit light for irradiating a specimen; a prism stuck to the specimen and configured to totally reflect the light emitted from the light source; a polarizing separation element configured to separate the light totally reflected by the prism into a first and second polarized light components that are orthogonal to each other; a wavelength dispersing element configured to disperse respective wavelength components of the first and second polarized light components that are separated by the polarizing separation element; an image capturing element configured to capture respective images of the first and second polarized light components that are dispersed by the wavelength dispersing element; and a processing unit configured to perform component analysis on the specimen by obtaining an absorbency at each wavelength by using an imaging signal output from the image capturing element.
