Abstract

See full text

Provided is a detection optical system that is provided with a dispersed-light detection function and that can increase the amount of detected light by enhancing the diffraction efficiency. A detection optical system is employed which includes a transmissive VPH diffraction grating that disperses fluorescence from a specimen into a plurality of wavelength bands; a rotating mechanism that rotates the VPH diffraction grating about an axial line that is perpendicular to an incident optical axis of the fluorescence from the specimen and an emission optical axis from the VPH diffraction grating; a light detection portion that detects the fluorescence from the specimen that has been dispersed by the VPH diffraction grating; and a correcting portion that corrects an incident position on the light detection portion in accordance with a displacement of the optical axis caused by the rotation of the VPH diffraction grating in synchronization with the rotating mechanism.
