Title (EN) ADAPTOR FOR AN IMAGE CAPTURE DEVICE FOR FUNDUS PHOTOGRAPHY
(FR) ADAPTATEUR DESTINÉ À UN DISPOSITIF DE CAPTURE D'IMAGE POUR LA PHOTOGRAPHIE DE FOND D'ŒIL
Abstract:
(EN) An adaptor (17) for attachment to an image acquisition device (15), the image acquisition device (15)having one or more camera apertures. The adaptor (17) has a housing (23) defining a passage (29) along which light waves may travel, an objective lens arrangement (39) within the passage, a secondary lens arrangement (41) within the passage positioned such that, when the adaptor (17) is attached to an image acquisition device (15), the secondary lens arrangement (41)is along a possible light pathway between the objective lens arrangement (39) and one or more camera apertures. The lens arrangements (39,41) are together configured to magnify an image of a pupil of the eye in proximity to a plane of one or more camera apertures and to focus light waves from a light source (43) at a point external of the adaptor (17) and offset from the optical axis of the objective lens arrangement (39).
(FR) L'invention concerne un adaptateur (17) destiné à être fixé à un dispositif d'acquisition d'image (15), ce dispositif d'acquisition d'image (15) comprenant au moins une ouverture d'appareil photographique. L'adaptateur (17) comprend un boîtier (23) définissant un passage (29) le long duquel des ondes lumineuses peuvent se déplacer, un agencement de lentilles d'objectif (39) dans le passage, un agencement de lentilles secondaires (41) dans le passage, positionné de telle sorte que, lorsque l'adaptateur (17) est fixé à un dispositif d'acquisition d'image (15), l'agencement de lentilles secondaires (41) se situe le long d'un trajet de lumière possible entre l'agencement de lentilles d'objectif (39) et au moins une ouverture d'appareil photographique. Les agencements de lentilles (39,41) sont conçus ensemble pour agrandir une image de la pupille d'un œil à proximité d'un plan d'au moins une ouverture d'appareil photographique et pour concentrer des ondes lumineuses provenant d'une source de lumière (43) au niveau d'un point externe de l'adaptateur (17) et décalé par rapport à l'axe optique de l'agencement de lentilles d'objectif (39).
