PROBLEM TO BE SOLVED: To provide a measuring apparatus capable of quickly acquiring a wide-band Raman spectrum at high resolution.SOLUTION: A stimulated Raman scattering measuring apparatus includes: first and second light generation means 2 for respectively generating first light and second light; an irradiation optical system 7 for combining the first light and the second light and irradiating a sample 8 with the combined light; and detection means 30 for detecting stimulated Raman scattering. The first light generation means drives at least one element out of, a light dispersion element for separating incident light into respectively different directions in accordance with an optical frequency, and an optical element included in a light guide optical system for guiding light from a first light source to the light dispersion element to change an incident angle of the incident light on the light dispersion element and extracts a part of light separated in the different directions, thereby the optical frequency of the first light can be varied. The second light generation means generates a plurality of pieces of second light having mutually different optical frequencies. A Raman spectrum is measured by changing the optical frequency of the first light in accordance with respective optical frequencies of the plurality of pieces of second light. |
