Abstract

Système optique destiné à la reproduction de la rétine. Il comporte deux groupes de lentilles, qui coopèrent pour former l'image, le premier groupe de lentilles étant au contact de la cornée de l'oeil du patient par l'intermédiaire du liquide lacrymal ou d'une solution physiologique de chlorure de sodium, et le deuxième groupe de lentilles étant séparé du premier par un interstice d'air et conjuguant la pupille du patient avec celle de l'observateur. Application aux examens ophtalmologiques de la rétine.
