Abstract
The invention is directed to a light measuring apparatus which is configured to generate broadband light from a laser beam emitted from a light source, the broadband light having a broader band than that of the laser beam, to divide the broadband light into a long wavelength component and a short wavelength component, to perform CARS measurement using the long wavelength component, and to perform fluorescence observation using the short wavelength component.
Claims13
A light measuring apparatus for measuring a sample using light, comprising:
- a broadband light generator configured to generate broadband light by allowing a laser beam to pass therethrough, the broadband light having a broader band than a band of the laser beam;
- a wavelength divider configured to divide the broadband light into a long wavelength component having a wavelength longer than that of the laser beam and a short wavelength component having a wavelength shorter than that of the long wavelength component;
- a multiplexer configured to multiplex the laser beam and the long wavelength component to generate multiplex light;
- a condensing optical system configured to concentrate the short wavelength component on the sample by concentrating the multiplex light on the sample;
- a spectroscope configured to detect Raman scattering light generated by emitting the multiplex light to the sample;
- and
- a fluorescence detector configured to detect fluorescence generated by emitting the short wavelength component to the sample.
