Description
Das in Korpuskularstrahlapparaten auf dem Leuchtschirm entstehende Bild wird durch Fenster von außen betrachtet. Es ist dabei erwünscht, daß eine möglichst große Anzahl von Personen das Bild gleichzeitig beobachten kann. Man hat daher in den Endbildtubus bisher häufig mehrere Löcher, die mit einzelnen Glasscheiben verschlossen waren, angebracht.That which arises in corpuscular beam devices on the luminescent screen Image is viewed from outside through window. It is desirable that one as possible large number of people can watch the image at the same time. You therefore have in the end image tube so far often several holes, which are closed with individual panes of glass were appropriate.
Die Erfindung löst diese Aufgabe in einfacherer und vollkommenerer Weise mit einer einzigen Glasscheibe. Es wird eine kreisrunde Scheibe i verwendet, die in der Mitte durchbohrt ist. An dieser Bohrung ist der Tubus 2 befestigt, welcher seinerseits beispielsweise beim Elektronenmikroskop zum Projektiv 3 überleitet. Am äußeren Rand der Ringscheibe i ist der Endbildtubus ,4 befestigt, welcher zum Leuchtschirm 5 bzw. zum Plattenstapel 6 überleitet, der in der Kamera 7 gelagert ist. Die Kreisringscheibe muß so kräftig ausgebildet sein, daß sie das Gewicht der darauf lastenden Apparaturteile tragen kann. Wenn also der Elektronenstrahl von oben nach unten gerichtet ist, so lastet auf dieser Scheibe das Gewicht der Vergrößerungslinsen der Objektkammer und des Strahlerzeugers. Ordnet man dagegen die Strahlrichtung nach Fig. i von unten nach, oben an, so lastet auf der Scheibe nur das Gewicht des Endbildtubus und der Kamera; dieses dürfte in der Regel kleiner sein als das der vorgenannten Teile, so daß die Erfindung mit besonderem Vorteil bei der von unten nach oben gehenden Strahlrichtung angewandt werden kann. Zur Verstärkung der Glasplatte kann man den Ring auch leicht gewölbt ausbilden, wobei man den Vergrößerungssinn bevorzugen wird, der nach der Leuchtschirmseite hin konkav ist.The invention solves this problem in a simpler and more perfect manner Way with a single pane of glass. A circular disk i is used, which is pierced in the middle. The tube 2 is attached to this hole, which in turn transferred to the projection lens 3, for example in the case of the electron microscope. At the outer edge of the annular disk i, the final image tube 4 is attached, which for Luminous screen 5 or transferred to the plate stack 6, which is stored in the camera 7 is. The circular ring disc must be so strong that it can bear the weight of the can carry loads of equipment. So if the electron beam from is directed upwards and downwards, the weight of the magnifying lenses rests on this disk the object chamber and the beam generator. On the other hand, if you order the direction of the beam according to Fig. i from bottom to top, only the weight of the weighs on the disc End image tube and the camera; this should usually be smaller than that of the aforementioned parts, so that the invention with particular advantage in the from below upward beam direction can be applied. To reinforce the glass plate the ring can also be made slightly arched, using the sense of enlargement will prefer, which is concave towards the luminescent screen side.
Die Oberflächen der Glasplatten kann man zur Vermeidung störender Spiegelungen mit reflexmindernden Schichten versehen.The surfaces of the glass plates can be used to avoid disturbing Provide reflections with anti-reflective layers.
Arbeitet man mit der Strahlrichtung von unten nach oben, so wird man unterhalb des Rundblickfensters einen Kragen 8 vorsehen, welcher entweder einen Rundspiegel oder eine Anzahl einzelner Spiegel trägt, durch deren Vermittlung man bei der schräg von oben nach unten hängenden Einblickrichtung den Leuchtschirm beobachtet. Die Dichtung 9 zwischen äußerem Rand der Glasplatte und Endbildtubus kann man leicht lösbar ausbilden, so daß man zum Wechsel des Plattenstapels das Gerät an dieser Stelle öffnen kann.If you work with the direction of the beam from bottom to top, you will Provide a collar 8 below the panoramic window, which either one Round mirrors or a number of individual mirrors, through whose mediation one carries observed the luminescent screen with the viewing direction hanging obliquely from top to bottom. The seal 9 between the outer edge of the glass plate and end-image tube can be easily form detachable, so that you can change the stack of plates the device on this Body can open.
