Abstract

In order to reduce light leak influencing the detection capability of a fluorescence imaging apparatus, an interference filter and an absorption filter on an emission-side filter section are arranged serially in the traveling direction of the fluorescence. The interference filter and the absorption filter that are in use for such an arrangement block the waveband light equivalent to the excitation light irradiated onto a sample while fully transmitting the waveband light equivalent to the fluorescence.
