Description

Einrichtung zum Verstellen des Pupillenabstandes binokularer Geräte Die Erfindung bezieht sich auf Einrichtungen züm Einstellen des Pupillenabstandes binokularer Geräte auf den Angenabstand des Beobachters nach dem deutschen Patent 1191601. Dabei stehen die Okulare fest, während in ihren Bildebenen Ablenkprismen um die optische Achse drehbar angebracht sind. Die mittlere Glasdicke der Prismen ist bei der Fehlerbehebung der Okulare zu berücksichtigen; sie erhöht gegebenenfalls die Glasdicken in der Nähe der Feldlinsen in störendem Ausmaß.Device for adjusting the interpupillary distance of binocular devices The invention relates to devices for adjusting the interpupillary distance of binocular devices to the distance between the eyes of the observer according to the German patent 1191601. The eyepieces are fixed, while deflecting prisms are rotatably mounted around the optical axis in their image planes. The average glass thickness of the prisms must be taken into account when troubleshooting the eyepieces; it possibly increases the glass thickness in the vicinity of the field lenses to a disruptive extent.

Die Erfindung schlägt deshalb vor, eine Prismenfläche als sammelnde Fläche auszubilden und als Feldlinse zu benutzen. Entweder wird eine Sammel- linse auf das Prisma aufgekittet oder die sammelnde Fläche unmittelbar am Prisma angebracht. Zweckmäßig geschieht das auf der senkrecht zur optischen Achse stehenden Fläche, damit zusätzlicher Astigmatismus vermieden wird.The invention therefore proposes to design a prism surface as a collecting surface and to use it as a field lens. Either a collecting lens cemented onto the prism or the collecting surface directly attached to the prism. This is expediently done on the surface perpendicular to the optical axis so that additional astigmatism is avoided.

Claims (2)

Patentansprüche: 1. Einrichtung zum Verstellen des Pupillenabstandes binokularer Geräte, deren Okulare in festem Achsenabstand voneinander stehen, wobei in jedem Strahlengang ein einziges Prisma vorgesehen ist, das von dem durchgehenden Lichtbündel ohne Reflexion durchsetzt wird, und wobei beide Prismen gegensinnig gleichzeitig um gleiche Beträge drehbar sind, nach Patent 1191601, dadurch gekennzeichnet, daß eine Prismenfläche eine sammelnde Fläche trägt und als Feldlinse dient. Claims: 1. Device for adjusting the interpupillary distance of binocular devices, the eyepieces of which are at a fixed axial distance from one another, with a single prism being provided in each beam path through which the light beam passes through without reflection, and both prisms can be rotated in opposite directions at the same time by the same amount are, according to patent 1191601, characterized in that a prism surface carries a converging surface and serves as a field lens. 2. Einrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die senkrecht zur optischen Achse stehende Prismenfläche die sammelnde Fläche trägt.2. Device according to claim 1, characterized in that the prism surface perpendicular to the optical axis carries the collecting surface.
