CA 2216463

A stereoscopic objective lens system for video endoscopic includes two full- diameter collimator doublets (110, 112) and a right/left stereo lens pair including a right and a left ball lens (114, 116). The two collimator doublets and the right/left stereo lens pair cooperate so that the collimator doublets present equal-angle ray pairs from symmetrically disposed object points (12) to the ball lenses of the right/left stereo lens pairs.

Système d'objectif stéréoscopique pour endoscopes vidéo, qui comporte deux doublets (110, 112) de collimateur de diamètre complet et une paire de lentilles stéréo droite/gauche comportant des lentilles (114, 116) sphériques droite et gauche. Les deux doublets de collimateur et la paire de lentilles sphériques droite et gauche coopèrent de manière à ce que les doublets de collimateur présentent des paires de rayons à angles égaux à partir de points (12) d'objets disposés de façon symétrique aux lentilles sphériques des paires de lentilles stéréo droite/gauche.
