Description
<Desc/Clms Page number 1>
Lichtbildwerfer für Auf-und Durchlicht.
Es ist bekannt, dass bei Epidiaskopen zum Übergang von einer Projektionsart zur andern das Verschieben von Lichtquelle und Reflektor bzw. auch der Beleuchtungslinse erforderlich ist. Bei dem Gegenstand der vorliegenden Erfindung wird ein Episkop in ein Epidiaskop verwandelt durch Entfernung eines Teiles der Gehäusevorderwand samt des ihm zugekehrten rückwärtigen Teiles des Lampenreflektors und durch Ansetzen eines Diaskopansatzes an die entstandene Öffnung der Gehäusevorderwand.
Die Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes. Fig. 1 zeigt den Apparat im Grundriss als Episkop, Fig. 2 stellt den Apparat als Epidiaskop im Grundriss dar.
Im Gehäuse 1 sind zwei Lampen 2 mit zweiteiligem Reflektor 3 in der Nähe der objektivseitigen Wand angeordnet, die das im Projektionsfenster der Rückwand befindliche Bild 4 beleuchten. Wird jener Teil der Vorderwand, der unmittelbar hinter der Lampe und dem Reflektor angeordnet ist und der das Ausstrahlen des Lichtes gegen die Wand verhindert, entfernt und an diese Stelle ein Diaskopansatz 5 gesetzt, so ist aus dem Episkop ein Epidiaskop geschaffen worden. Nun ist die Epilampe zu einer Epidialampe geworden, die gleichzeitig das Epi-und Diabild beleuchtet. Soll die Epiprojektion zeitlich von der Diaprojektion getrennt werden, so geschieht dies nicht durch Drehen der Lampe, sondern durch blosses Abdecken des Dia-bzw. Epiobjektivs.

Light projector for incident and transmitted light.
It is known that in the case of epidiascopes it is necessary to move the light source and reflector or also the illumination lens in order to transition from one type of projection to another. In the subject matter of the present invention, an episcope is converted into an epidiascope by removing part of the front wall of the housing together with the rear part of the lamp reflector facing it and by attaching a diascope attachment to the opening in the front wall of the housing.
The drawing is an embodiment of the subject matter of the invention. Fig. 1 shows the apparatus in plan as an episcope, Fig. 2 shows the apparatus as an epidiascope in plan.
In the housing 1, two lamps 2 with a two-part reflector 3 are arranged in the vicinity of the objective-side wall, which illuminate the image 4 located in the projection window of the rear wall. If that part of the front wall which is arranged immediately behind the lamp and the reflector and which prevents the light from emitting against the wall is removed and a diascope attachment 5 is placed at this point, an epidiascope has been created from the episcope. The epilamp has now become an epidial lamp that simultaneously illuminates the epi and slide image. If the epiprojection is to be separated in time from the slide projection, this is not done by turning the lamp, but by simply covering the slide or slide. Epi lens.
