RAMAN SCATTERING MEASURING APPARATUS AND RAMAN SCATTERING MEASURING METHOD

摘要

The Raman scattering measuring apparatus includes a first light generator to produce a first light, a second light generator to produce a second light having a frequency different from that of the first light, an optical system to focus the first and second lights to a sample, and a detector to detect the first or second light intensity-modulated by Raman scattering. The first light generator includes a wavelength extractor that performs a wavelength filtering to extract light of an extraction wavelength from light in a wavelength range including the extraction wavelength and an amplification of the light extracted by the wavelength filtering. The wavelength extractor performs a first filtering on an entering light, a first amplification on the light extracted by the first filtering, a second filtering on the light amplified by the first amplification and a second amplification on the light extracted by the second filtering.
