Abstract

Die Erfindung betrifft ein optisches System für eine Funduskamera zur reflexfreien Ophthalmoskopie, welches einen Strahlengang mit im Wesentlichen gemeinsam für die Beleuchtung und die Beobachtung oder die Aufnahme genutzten, brechenden und reflektierenden, optischen Elementen aufweist. Zur Beleuchtung und Abbildung des Fundus ist ein im Wesentlichen aus mehreren reflektierenden optischen Elementen, in Form von Spiegeln (1 und 2), bestehendes, abbildendes Spiegelsystem vorgesehen, wobei mindestens ein optisches Element, beispielsweise Spiegel (2), als Freiformspiegel mit einer abbildenden, reflektierenden Freiformfläche ausgebildet ist. Dabei sind die optischen Elemente in genau definierter Position und Lage zueinander derart in einem Gehäuse angeordnet, dass in einem weiten Dioptrienbereich der zu untersuchenden Patientenaugen (9) eine Abbildung der reflektierenden Flächen der optischen Elemente auf das Bild der abgebildeten Retina vermieden wird.
