SPECTROSCOPIC OBSERVATION DEVICE, ENDOSCOPE SYSTEM, AND CAPSULE ENDOSCOPE SYSTEM

摘要

A spectroscopic observation device enables proper observation by respectively meeting 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 to be observed. The spectroscopic observation device comprises: an excitation light source (8) to irradiate excitation light toward an observation target; a spectroscopic element (12) which can separate fluorescence emitted out of the observation target by the irradiation of the excitation light coming from the excitation light source (8), into a plurality of types of fluorescence wavebands having the same center wavelength and different pass bands; and an image pickup section (13) which takes an image of the fluorescence separated by the spectroscopic element (12).
