Description
Lichtelektrische Zelle mit Strahlenfilter Die vorliegende Erfindung bezieht sich auf lichtempfindliche Zellen derjenigen Art, bei denen die Belichtung senkrecht zur Stromrichtung erfolgt. Diese Zellen verwendet man häufig in Verbindung mit Strahlenfiltern, um z. B. bei Empfangsgeräten für Lichtzeichen die Wirkung des Tageslichtes auf die Zellen auszuschalten oder die Zellen vor Strahlen zu schützen, durch die ihre Lebensdauer ungünstig beeinflußt werden könnte. Dabei hat man im allgemeinen Glas- oder Gelatinefilter oder auch Hartgummifilter u. dgl. angewendet, die man mit der Zelle selbst -oder mit @ der Fassung .eines optischen Systems verband, d:is gewöhnlich zum Abbilden der Strahlungsquelle auf der Zelle vorgesehen ist.Radiation filter photoelectric cell The present invention refers to photosensitive cells of the kind that are exposed to light takes place perpendicular to the current direction. These cells are often used in conjunction with radiation filters to e.g. B. in receiving devices for light signals the effect of the To switch off daylight on the cells or to protect the cells from radiation, which could adversely affect their service life. In the general glass or gelatin filters or hard rubber filters and the like used, connected to the cell itself or to the frame of an optical system, d: is usually intended for imaging the radiation source on the cell.
Besitzt die Zelle einen strahlendurchlässigen Träger für den lichtempfindlichen Stoff, durch den hindurch die Bestrahlung erfolgt, so wird der Erfindung gemäß der Träger für den lichtempfindlichen Stoff selbst als Filter ausgebildet. Es ergibt sich dadurch nicht nur der Vorteil, daß die Zelle unter allen Umständen, auch wenn sie noch nicht in ein Empfangsgerät eingebaut ist, gegen unerwünschte Strahlen geschützt ist, und zwar ohne daß es möglich ist, daß die Anbringung des Filters versehentlich unterbleibt, sondern dieser Vorteil wird .auch bei größtmöglicher Einfachheit des Zellenaufbaues erreicht. Dazu kommt, daß durch Fortfall von zwei reflektierenden Flächen ein nicht unerheblicher Lichtgewinn (etwa 8 0,'o) erzielt wird.The cell has a radiolucent support for the light-sensitive Substance through which the irradiation takes place, so the invention according to the Carrier for the photosensitive substance itself designed as a filter. It results This not only has the advantage that the cell under all circumstances, even if it has not yet been built into a receiving device and is protected against undesired radiation without it being possible that the attachment of the filter is accidentally does not take place, but this advantage is retained even with the greatest possible simplicity of the Cell structure achieved. In addition, the omission of two reflective Surfaces a not inconsiderable gain in light (about 8 0, 'o) is achieved.
Als Baustoff für die neuen Filter kommt vorwiegend Glas in Frage. Es hat sich gezeigt, daß dasselbe geeignet ist, sowohl in verschiedenster Weise als Filter ausgebildet zu werden als auch zugleich als Träger für die Elektroden und den lichtempfindlichen Stoff zu dienen.The main building material for the new filters is glass. It has been shown that the same is suitable, both in the most varied of ways to be designed as a filter and at the same time as a carrier for the electrodes and to serve the photosensitive fabric.
In der Zeichnung ist beispielsweise eine der Erfindung entsprechende Thalliumsulfidzelle in Ansicht dargestellt, bei der ein im wesentlichen nur rote und ultrarote Strahlen hindurchlassendes Glasfilter a vorgesehen ist, das zugleich als Träger für, das Thalliumsulfid und die Elektroden dient.In the drawing, for example, one corresponding to the invention is shown Thallium sulfide cell shown in view, in which an essentially only red and a glass filter a permitting ultrared rays is provided, which is at the same time serves as a carrier for, the thallium sulfide and the electrodes.
