Title (EN) STEREO-ENDOSCOPE
(FR) ENDOSCOPE STÉRÉOSCOPIQUE
(JA) 立体内視鏡
Abstract:
(EN) A pair of left and right rod lenses (19) is disposed in the insertion part (10) of a stereo-endoscope (3), and an objective optical system (18), consisting of a stationary lens (22) and a moveable lens (23), is disposed at the tip thereof. The moveable lens (23) is moved by a motor (24) to change the distance to the stationary lens (22). Consequently, the focal length of the objective optical system (18) can be changed, whereby sites with different focal points can be observed without shifting the stereo-endoscope (3) forward and back as a whole.
(FR) Selon la présente invention, une paire de lentilles barreaux gauche et droite (19) est disposée dans la partie insertion (10) d’un endoscope stéréoscopique (3), et un système optique à objectif (18) consistant en une lentille fixe (22) et une lentille mobile (23) est disposé à l’extrémité de celle-ci. La lentille mobile (23) est déplacée par un moteur (24) pour changer la distance par rapport à la lentille fixe (22). En conséquence, la longueur focale du système optique à objectif (18) peut être modifiée, des sites à points focaux différents pouvant être observés sans décaler l’endoscope stéréoscopique (3) vers l’avant ni vers l’arrière dans sa totalité.
(JA)  立体内視鏡3の挿入部10には左右一対のロッドレンズ19が設けられ、その先端部に固定レンズ22と可動レンズ23から成る対物光学系18が設けられている。可動レンズ23はモータ24により可動し、固定レンズ22との距離が変化する。従って、対物光学系18の焦点距離を変えることができ、立体内視鏡3全体を前後に移動させなくても、焦点の異なる部位を観察することができる。
