Title:
FLUORESCENT LIGHT OBSERVATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/126000
Kind Code:
A1
Abstract:
This fluorescent light observation device (1) comprises: a light source unit (3) which projects illumination light (L), which includes excited light, upon a living body tissue (X); a return light image generating unit (61) which photographs return light of the illumination light (L) from the living body tissue (X) and generates a return light image (G1); and a fluorescent light image generating unit (62) which photographs fluorescent light from the living body tissue (X) and generates a fluorescent light image (G2). The illumination light (L) is visible light which does not include at least a portion of a wavelength region of 490-540nm, the excited light has a portion of the wavelengths of the illumination light (L), and fluorescent light is emitted of the wavelength which is included in the at least partial wavelength region.
