Description

Autokollimations sp ektralgerät Die Erfindung betrifft ein Autokollimationsspektralgerät mit zwei wahlweise benutzbaren, auf einer drehbaren Halteeinrichtung befestigten Prismen.Autocollimation spectral device The invention relates to an autocollimation spectral device with two optionally usable, fixed on a rotatable holding device Prisms.

In Autokollimationsspektralgeräten werden Prismen mit verspiegelten Flächen benötigt. Sofern diese Prismen aus Glas bestehen, ist die Kollimationsverspiegelung leicht aufzubringen. Dies ist jedoch z. B. bei aus Salzkristallen gefertigten Prismen nicht möglich. In solchen Fällen mußte man sich damit helfen, daß man ein solches Prisma mit einem parallel zu seiner Austrittsfläche angeordneten zusätzlichen Autokollimationsspiegel kombinierte. In autocollimation spectral devices, prisms are mirrored Space required. If these prisms are made of glass, the collimation is mirrored easy to apply. However, this is e.g. B. in prisms made of salt crystals not possible. In such cases one had to help oneself by having one Prism with an additional autocollimation mirror arranged parallel to its exit surface combined.

Da man in den genannten Geräten wahlweise ein Glas- oder ein Kristallprisma benötigt, wird ein zusätzlicher Spiegel dadurch entbehrlich, daß gemäß der Erfindung die beiden Prismen auf einer um etwa 1800 drehbaren Halteeinrichtung so befestigt sind, daß nach Drehung die verspiegelte Rückseite des einen Prismas gleichzeitig auch als Autokollimationsspiegel für das andere Prisma dient. Since you can choose between a glass or a crystal prism in the devices mentioned required, an additional mirror is dispensed with that according to the invention the two prisms are attached to a holding device that can be rotated by about 1800 are that after rotation the mirrored back of one prism at the same time also serves as an autocollimation mirror for the other prism.

Ein Ausführungsbeispiel des Gegenstandes der Erfindung ist in der Zeichnung dargestellt, und zwar zeigt Fig. 1 ein Prismenwechselsystem und Fig. 2 das gleiche um 1800 gedrehte System. An embodiment of the subject matter of the invention is in In the drawing, FIG. 1 shows a prism changing system and FIG. 2 the same system turned around 1800.

Wie die Fig. 1 und 2 darstellen, befinden sich auf einer um 1800 drehbaren Scheibe 1 zwei Prismen 2 und 3. Gemäß Fig. 1 befindet sich das Prisma 2 in Arbeitsstellung. Es besteht aus verspiegelbarem Glas und enthält eine aufgedampfte, nach beiden Seiten spiegelnde Fläche 4, an der ein durch die gegenüberliegende Fläche 5 in das Prisma 2 hineintretender Lichtstrahl 6 reflektiert wird. As shown in FIGS. 1 and 2, one is around 1800 rotatable disc 1, two prisms 2 and 3. According to FIG. 1, the prism is located 2 in working position. It consists of mirrorable glass and contains a vapor-deposited, surface 4 reflecting to both sides, on which one through the opposite surface 5 light beam 6 entering the prism 2 is reflected.

Durch Drehen der Scheibe 1 um 1800, so daß an Stelle der Marke A sich die Marke B am Zeiger 7 be- findet, liegt das Prisma 3 in Arbeitsstellung. Dieses Prisma besteht aus einem nicht verspiegelbaren Material. Die Anordnung der beiden Prismen 2 und 3 ist so getroffen, daß gemäß der Erfindung die Spiegelfiäche 4 des Prismas 2 parallel zur Fläche 8 des Prismas 3 liegt und gleichzeitig auch als Autokollimationsspiegel für den in das Prisma 3 eintretenden Lichtstrahl 9 dient. By turning the disk 1 by 1800, so that in place of the mark A mark B on pointer 7 is finds, the prism 3 is in the working position. This Prism is made of a non-reflective material. The arrangement of the two Prisms 2 and 3 is made so that, according to the invention, the mirror surface 4 of the Prism 2 is parallel to the surface 8 of the prism 3 and at the same time as an autocollimation mirror for the light beam 9 entering the prism 3 is used.
