Abstract
(EN)
This endoscope is provided with: imaging optics that comprises a plurality of optical components constituting a light path and that causes light from a subject to enter the light path and form an image, wherein the light includes fluorescent light generated by excitation light that causes the emission of fluorescent light from a fluorescent drug that has been administered to the subject; an image sensor that performs photoelectric conversion of the light from the subject imaged by the imaging optics; and an excitation light cutoff filter, only one of which is disposed in the interior of the imaging optics, that blocks the transmission of at least a portion of the excitation light from the light from the subject.

La présente invention concerne un endoscope pourvu : d’éléments d'optique d’imagerie qui comprennent une pluralité de composants optiques constituant un trajet lumineux et qui amène la lumière provenant d’un sujet à pénétrer dans le trajet lumineux et former une image, la lumière comprenant de la lumière fluorescente générée par la lumière d’excitation qui provoque l’émission de lumière fluorescente à partir d’un médicament fluorescent qui a été administré au sujet ; un capteur d’image qui effectue la conversion photoélectrique de la lumière à partir du sujet imagé par les optiques d’imagerie ; et un filtre de coupure de lumière d’excitation, dont uniquement un est disposé dans l’intérieur des optiques d’imagerie, qui bloque la transmission d’au moins une partie de la lumière d’excitation depuis la lumière provenant du sujet.
