Abstract: Provided is a protection device including a cover member that is disposed on a stage of a microscope main unit, which is provided with a shutter that can block the entry of laser light into an objective lens from a total-reflection illumination optical system, so as to cover a specimen, and that can be opened and closed; and an open/close sensor that detects open and closed states of the cover member and that outputs a drive signal that causes the shutter to block the laser light when the cover member is detected to be in the open state, wherein the cover member has an opening at, in the closed state, a position away from a track along an optical path of the laser light that has been focused by the total-reflection illumination optical system and that has passed through the specimen.

Abstract: 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.
