A fluorescence microscope (101) includes an objective lens (103), light projecting unit (105), and CCD camera (122). The light projecting unit (105) is provided with a rear converter (109), wavelength multiplexing device (110), first light source unit (111), and second light source unit (115). Both a first light-emitting diode (112) of the first light source unit (111) and a second light-emitting diode (116) of the second light source unit (115) are in a positional relationship conjugate to the rear focus of the objective lens (103). A photometric device is placed on the opposite side of the objective lens (103) to a specimen (121). The photometric device includes a pinhole (126) and photodiode (127). A power supply device (119) controls driving currents for the first light-emitting diode (112) and second light-emitting diode (116) on the basis of the photometric value obtained from the photodiode (127). <IMAGE> |
