Justiereinrichtung für Prismendoppelfernrohre nach Porro.
Es ist eine Einrichtung zum Justieren von Porro-Doppelfernrohren bekannt, durch welche die Einzelprismen auf ihrer Sitzfläche in ihrer Längsrichtung verschoben werden.
Auch ist es nicht neu, jedes Prisma durch zwei auf die Kathetenflächen wirkende Druck- stücke von der Deckelseite des Fernrohres zu verschieben.
Die vorliegende Erfindung erzielt die gleiche Wirkung wie die eben erwähnte Einrichtung, ohne jedoch die totalreflektierenden, empfindlichen Prismenflächen zu benutzen und unter Verwendung nur @i@es Stellor@@@s für jedes Prisma.
Zu diesem Zweck wird als Angriffspunkt für die Bewegung des Prismas die Dachfacette e des letzteren gewählt, die zweckmässig-aber nicht notwendig-mit einer Einkerbung (Einschliff) versehen ist. An diese Dnchfacette bzw. den Einschliff greift ein Ansatz

Adjustment device for double prism telescopes according to Porro.
A device for adjusting Porro double telescopes is known, by means of which the individual prisms are displaced in their longitudinal direction on their seat surface.
It is also not new to move each prism from the cover side of the telescope by means of two pressure pieces acting on the cathetus surfaces.
The present invention achieves the same effect as the device just mentioned, but without using the totally reflective, sensitive prismatic surfaces and using only @ i @ es Stellor @@@ s for each prism.
For this purpose, the roof facet e of the latter is chosen as the point of application for the movement of the prism, which is expediently - but not necessary - provided with a notch (cut). An approach engages this thin facet or the bevel
EMI1.1
can be moved in its longitudinal direction from the outside. The other end of the retaining spring is bifurcated and comprises a screw t, which is used to hold the spring after adjustment
