Noise in a fluorescence image acquired during fluoroscopy is eliminated to present a clear fluorescence image, and the relative positional relationship between the fluoroscopy unit and the specimen can be recognized even while fluoroscopy is in progress. A dark box apparatus for fluoroscopy includes: a dark-box main body enclosing a specimen and a fluoroscopy unit for illuminating the specimen with excitation light with a first spectral band and for detecting fluorescence with a second spectral band generated by the specimen; an illumination light source disposed in the dark-box main body to emit light with a third spectral band different from the first spectral band and the second spectral band; and an observation window disposed in the dark-box main body, the observation window being capable of transmitting light with a fourth spectral band which includes at least part of the third spectral band and does not include the first spectral band and the second spectral band.
