Abstract

Système optique pour l'éclairement du fond de l'oeil et pour la reproduction sur celui-ci d'images de repères-témoins. Dans le parcours de la lumière entre une source lumineuse 6 et un objectif ophtalmologique 14, il est prévu un collecteur 8 et un repère-témoin 4, et un système 1, 2, 3 reproduisant l'image est disposé entre le repère-témoin 4 et l'objectif ophtalmologique 14 de manière à pouvoir être déplace le long de l'axe optique. L'invention s'applique notamment à la construction d'ophtalmoscopes à main.
