Abstract: Example embodiments relate to a circular dichroism fluorescent microscope having a confocal section. In the circular dichroism fluorescent microscope, a circularly polarizing/modulating section converts, into right and left circularly polarized lights, a light beam emitted from a light source. As such, the obtained right and left circularly polarized lights are focused on a sample so that the sample is irradiated with the right and left circularly polarized lights. Then, an optical lens focuses fluorescence emitted from the sample. Further, a wavelength selecting section transmits only fluorescence having a predetermined wavelength. Subsequently, the fluorescence having passed through the wavelength selecting section is detected.

Abstract: According to a circular dichroism fluorescent microscope 100, in one embodiment of the present invention, it is possible to analyze, by using a small amount of a sample and directly in a living organism, a high-order structure of the sample such as a biomolecule, for example, protein and the like. The circular dichroism fluorescent microscope includes a confocal section. In the circular dichroism fluorescent microscope, a circularly polarizing/modulating section converts, into right and left circularly polarized lights, a light beam emitted from a light source. Thus obtained right and left circularly polarized light is focused on the sample so that the sample is irradiated with the right and left circularly polarized lights. Then, an optical lens focuses fluorescence emitted from the sample. Further, a wavelength selecting section transmits only fluorescence having a predetermined wavelength. Subsequently, the fluorescence having passed through the wavelength selecting section is detected.
