Abstract:
1. A laser-scanning microscope comprising: a laser light source unit; an optical fiber that transmits excitation light or illumination light from the laser light source unit; a collimator optical system that substantially collimates the excitation light or illumination light from the optical fiber; an optical scanning unit that scans the excitation light or illumination light from the collimator optical system onto a specimen; a pupil projection optical system that images the excitation light or illumination light from the optical scanning unit at an intermediate image position; an objective optical system that re-images the intermediate image of the excitation light or illumination light imaged in the pupil projection optical system onto the specimen; and a detection optical system that detects fluorescence or reflected light emitted from the specimen, wherein, when the numerical aperture of laser light emitted from the pupil projection optical system at the intermediate image position is NAp
