ABSTRACT:
To accurately obtain fluorescence intensity in a variable passband. Provided is a fluorescence observation apparatus including an excitation light source that emits excitation light; a Fabry-Perot resonator including a variable passband in which the wavelength of light that passes therethrough changes with changes in distance between the surfaces of optical members opposing each other with a distance therebetween, a fixed passband in which the wavelength of light that passes therethrough does not change irrespective of changes in the distance between the surfaces, and a transition band therebetween; an excitation-light cut filter that blocks passage of the excitation light; a band cut filter having a cut-off band including the transition band and not including the wavelength of the excitation light; and a photodetector that detects fluorescence that has passed through the Fabry-Perot resonator, the excitation-light cut filter, and the band cut filter.
