Abstract
Provided is a spectroscopic detector including: a light source for generating polychromatic light; a single diffraction grating; an excitation optical system for guiding the light from the light sourceonto the diffraction grating, for selecting one wavelength from the light diffracted by the diffraction grating, and for casting the selected wavelength of light into a sample as excitation light; a detection optical system for guiding observation light emitted from the sample irradiated with the excitation light onto the diffraction gratingto disperse the observation light; and a photodetectorfor detecting the observation light dispersed by the detection optical system. By using one diffraction gratingin both the excitation optical system and the detection optical system, the number of diffraction gratings is reduced, whereby both the cost reduction and the downsizing of the device are achieved.
