Abstract
An incident-light fluorescence microscope including: (i) a transmission illuminating optical system which has a first optical member for receiving light emitted from a light source and extracting transmitted light and which irradiates the transmitted light onto a sample, and (ii) an observation optical system which has an objective lens and a second optical member and which is positioned closer to the objective lens than the sample. An incident-light fluorescence illuminating optical system is provided in the observation optical system, wherein the first optical member has a peak of transmittance at a wavelength longer than the fluorescent wavelength, and the second optical member selectively modulates only a wavelength transmitted through the first optical member.
