摘要：
Provided is an endoscope expansion device which makes it possible for a single endoscope to be expanded to become an endoscope having a plurality of observation functions.An endoscope (20) is provided with an objective lens (22), a plurality of relay lens systems (24), and an eyepiece (26), and an exit pupil (Exp) is formed immediately downstream of the eyepiece (26). A housing (39) of the endoscope expansion device is attached to the eyepiece (26) by means of an attachment portion (32). A relay optical system (34) and a branching portion (36) which form a functionalization platform (31) are provided in the housing (39). The endoscope expansion device (30) uses the relay optical system (34) to move the exit pupil (Exp) of the endoscope (20) to a position away from the eyepiece (26). Light that has propagated along an optical path that has been caused to branch by the branching portion (36) is received by a light receiving portion (38). Employing the endoscope expansion device (30) with this configuration makes is possible for the single endoscope (20) to be expanded to become an endoscope having a plurality of observation functions.La présente invention concerne un dispositif dexpansion dendoscope qui permet à un endoscope unique dêtre déployé de façon à devenir un endoscope ayant une pluralité de fonctions dobservation. Un endoscope (20) est pourvu dune lentille dobjectif (22), dune pluralité de systèmes de lentilles de relais (24), et dun oculaire (26), et une pupille de sortie (Exp) est formée immédiatement en aval de loculaire (26). Un boîtier (39) du dispositif dexpansion dendoscope est fixé à loculaire (26) au moyen dune partie de fixation (32). Un système optique de relais (34) et une partie de branchement (36) qui forment une plate-forme de fonctionnalisation (31) sont disposés dans le boîtier (39). Le dispositif dexpansion dendoscope (30) utilise le système optique de relais (34) pour déplacer la pupille de sortie (Exp) de lendoscope (20) vers une position
