Title (EN) OBJECTIVE LENS FOR AN ENDOSCOPE OF THE RETROFOCUS TYPE HAVING AN ACHROMAT
(FR) SYSTÈME DE LENTILLE D'OBJECTIF
Abstract: front page image
(EN)An objective lens (30) for an endoscope comprises a front (41a) and a rear (41b) optical sub-system and an aperture stop (51) there between. The rear optical sub-system (41 b) comprises a compound achromatic component (LR2, LR3) and a rear positive lens (LR4) disposed between said component and the image plane of the system in close proximity to the image plane. The rear positive lens (LR4) satisfies the following condition: fR ≥ 4f where f is the focal length of the total objective lens and fR is the focal length of the rear positive lens (LR4).
(FR)L'invention concerne un système optique de lentille d'objectif pour un endoscope. Le système inclut un sous-système optique avant et un sous-système optique arrière, et un diaphragme placé entre ceux-ci. Le sous-système optique arrière comporte un composant achromatique composé et une lentille positive arrière disposée entre ledit composant et le plan d'image du système, à proximité étroite du plan d'image. La lentille positive arrière remplit la condition suivante : fR ≥ 4f, où f est la distance focale composite de la totalité du système et fR est la distance focale de la lentille positive arrière.
