Abstract

L'invention concerne un endoscope comportant un système d'observation auxiliaire, à l'aide duquel on peut régler l'image par l'intermédiaire de l'optique de l'endoscope, pour l'observateur principal et l'observateur auxiliaire ou bien une caméra de cinéma ou de télévision. Le dispositif diviseur de rayonnement comprend deux plaquettes minces de verre comportant individuellement une partie partiellement réfléchissante ou bien placées l'une en regard de l'autre par leur partie partiellement réfléchissante et qui peuvent être amenées en commun et suivant un certain angle dans le trajet du rayonnement de l'endoscope. Application au perfectionnement des endoscopes avec système d'observation auxiliaire.
