ABSTRACT:
A reflected fluorescence microscope is used to observe a fluorescent image of a stained specimen by reflected illumination, and includes a light source, an excitation filter for converting light from the light source into a plurality of narrow-band excitation lights, a dichroic mirror for reflecting the narrow-band excitation lights emerging from the excitation filter toward the specimen and transmitting therethrough the light emerging from the specimen, an absorption filter for absorbing an extra wavelength component from light emerging from the dichroic mirror and transmitting therethrough a wavelength component of the fluorescent image, an optical system for forming the fluorescent image of the specimen from the wavelength component transmitted through the absorption filter, and a transmission wavelength shifting filter for adjusting the ratio of the quantities of light in units of fluorochromes.
