Description

Parallelsichtiges Umkehrprismensystem Die Erfindung betrifft ein parallelsichtiges Umkehrprismensystem mit nur zwei an Luft grenzenden Strahlendurchtrittsflächen und sechs Spiegelflächen, die so angeordnet sind, daß sämtliche Spiegelungen in einer Ebene erfolgen, und die sämtlich totalreflektierend sind, also keine Versilberung erfordern, wobei zwei von ihnen ein Dach bilden.Parallel vision erecting prism system The invention relates to a parallel vision system Erecting prism system with only two air passage surfaces and six mirror surfaces, which are arranged so that all reflections in one Level, and which are all totally reflective, so no silver plating require, with two of them forming a roof.

Um ein Prismensystem dieser Art zu er halten, bei dem der eintretende und der austretende Strahl einen verhältnismäßig geringen Abstand voneinander haben, gegebenenfalls sogar den Abstand Null, wird nach der Erfindung -eine der nicht zum Dach gehörenden Spiegelflächen als eine jener beiden Strahlendurchtrittsflächen gewählt, und es ist die Anordnung des Daches in an sich bekannter Weise so getroffen, daß ein durch diese Durchtrittsfläche in das Prismensystem eingetretener Strahl zuerst das Dach trifft und darauf unmittelbar an dieser Durchtrittsfläche gespiegelt wird. Außerdem ist der von dieser Durchtrittsfläche und der ihr benachbarten einfachen Spiegelfläche gebildeteWinkel kleiner als i i o?.To keep a prism system of this type, in which the entering and the exiting jet have a relatively small distance from each other, possibly even the distance zero, according to the invention - one of the not to Roof belonging mirror surfaces as one of those two beam passage surfaces selected, and the arrangement of the roof is made in a manner known per se, that a beam that has entered the prism system through this passage area first hits the roof and then reflected directly on this passage area will. In addition, that of this passage area and the one adjacent to it is simple The angles formed by the mirror surface are smaller than i i o ?.

In dem gezeichneten Ausführungsbeispiel besteht das Prismensystem aus zwei miteinander verkitteten Teilen 1 und II. Die Strahlendurchtrittsflächen sind mit a und b bezeichnet, von denen a gleichzeitig als Spiegelfläche dient. Außerdem sind noch an Spiegelflächen vorhanden das Dach c, das der Durchtrittsfläche a benachbart liegt und unter einem Winkel von 2y° dagegen geneigt ist, und drei einfache Spiegelflächen d, e und f. Sämtliche Spiegelflächen sind unversilbert.In the illustrated embodiment, the prism system consists of two parts 1 and II cemented to one another. The beam passage areas are denoted by a and b , of which a simultaneously serves as a mirror surface. In addition, the roof c, which is adjacent to the passage surface a and is inclined at an angle of 2y ° to it, and three simple mirror surfaces d, e and f are also present on mirror surfaces. All mirror surfaces are un-silvered.
