SPECTROSCOPIC OBSERVATION DEVICE, ENDOSCOPE SYSTEM, AND CAPSULE ENDOSCOPE SYSTEM

摘要

A spectroscopic observation device enables proper observation to meet the observation condition where easy-to-observe image with high S/N ratio is preferable and the observation condition where it is preferable to restrain interfusion of any other fluorescent components even when fluorescence of the same wavelength is observed. The spectroscopic observation device includes an excitation light source (8) to irradiate excitation light toward an object being photographed, a spectroscopic element (12) which can separate the multiple-waveband fluorescence with the same center wavelength and different pass bands from the fluorescence emitted out of the object being photographed by irradiation of the excitation light from the excitation light source (8), and an imaging section (13) to image the fluorescence separated by the spectroscopic element (12).
