An optical system (10) comprises a camera (11) having an imaging means that in use faces downwardly, and an optical assembly. The optical assembly includes a support (14) that extends ouwardly from the camera (11) and which has a lumen therethrough to allow transmission of light through the support (14) to the imaging means of the camera (11). The assembly further includes an optical unit (16) mountable to the support (14) and movable relative thereto towards and away from the imaging means of the camera (11). The optical unit (16) includes at least one lens (17) and a mirror assembly (21, 22) adapted to reflect at least some light entering the unit (16) that is at approximately a right angle to the orientation of the camera (11), through the lens (17) and into the lumen of the support (14) to the imaging means. The system (10) can be mounted to a headpiece worn by a user, such as a surgeon.

L'invention concerne un système optique (10) comprenant une caméra (11) qui présente un moyen d'imagerie orienté, lors de l'utilisation, vers le bas, ainsi qu'un ensemble optique. Ce dernier comprend un support (14) qui s'étend vers l'extérieur à partir de la caméra (11) et dans lequel est pratiquée une lumière destinée à permettre la transmission lumineuse à travers le support (14) vers le moyen d'imagerie (14) de la caméra (11). Cet ensemble comprend en outre une unité optique (16) pouvant être montée sur le support (14) et pouvant se déplacer par rapport à ce dernier, pour s'approcher et s'éloigner du moyen d'imagerie de la caméra (11). L'unité optique (16) comprend au moins une lentille (17) et un ensemble miroir (21, 22) conçu pour réfléchir au moins une partie de la lumière pénétrant dans l'unité (16), de manière approximativement perpendiculaire à l'orientation de la caméra (11), à travers la lentille (17) et dans la lumière du support (14) en direction du moyen d'imagerie. Ce système (10) peut être monté sur un élément porté sur la tête de l'utilisateur, notamment d'un chirurgien.
