Description
Strahlungssammler für Empfänger mit strahlungsempfindlichem Spitzkontakt Es ist bereits bekannt, einen in einer Hülle befindlichen Kontaktdetektor durch eine Linse hindurch seitlich zu bestrahlen. Bei einer solchen Anordnung fällt das Licht immer mehr oder weniger streifend auf die lichtempfindliche Schicht, wodurch ein geringerer Wirkungsgrad der einfallenden Strahlung bedingt ist. Außerdem führt eine leicht mögliche geringe Verschiebung der Linse in ihrer Fassung .schon zur Sammlung des Lichtstrahlenbündels .an einem Punkt, der nicht mehr mit der lichtempfindlichen Stelle übereinstimmt.Radiation collector for receivers with radiation-sensitive pointed contact It is already known to use a contact detector located in a sheath irradiate laterally through a lens. With such an arrangement, that is not the case Light always more or less grazing on the light-sensitive layer, whereby a lower efficiency of the incident radiation is caused. It also leads a slight possible slight displacement of the lens in its frame .schon zur Collection of the light beam. At a point which is no longer with the light-sensitive Position matches.
Es ist weiterhin bekanntgeworden, eine Kristallfl.äche und die Metallspitze eines Detektors durch ein. geeignetes flüssiges Mittel zusammenzukitten, damit ihre gegenseitige Lage dauernd erhalten bleibt, um eine Schädigung der ,an sich guten Detektorstellung zu vermeiden. Wenn dabei eine ebene Kittfläche vorhanden ist, ,auf die Lichtstrahlen auffallen, so ändert sich der Strahlengang nicht wesentlich. Ist die Kittfläche dagegen gekrümmt, so kann der Lichteinfall nur in einem besonderen Falle günstig beeinfllußt werden. Seine Wirkung ist jedenfalls immer unbestimmt und gering.It has also become known, a crystal face and the metal tip of a detector through a. suitable liquid agent to cement together so that their mutual situation is permanently preserved in order to damage the, in itself good To avoid detector position. If there is a flat putty surface,, on If the rays of light fall, the path of the rays does not change significantly. is If the cement surface is curved, however, the incidence of light can only be in a special one Case are favorably influenced. In any case, its effect is always indefinite and low.
Um nun für die Zwecke des Strahlungsempfanges bei Verwendung von Empfängern mit einem oder mehreren strahlungsempfindliehen Spitzkontakten die :auftreffende Strahlung nach punktförmigen Stellen des Empfängers hinzuleiten, ist gemäß der Erfindung der .die Kontaktspitze aufweisende Metalldraht unmittelbar vor seiner Berührungsstelle mit der strahlungsempfindlichen Schicht oder in ihrer Nähe durch ein derart sammelndes optisches System, das nur von dem Metalldraht getragen wird, hindurchgeführt, daß die auftreffenden Strahlen in einem Punkt an der Berührungsstelle der Kontaktspitze vereinigt werden.To now for the purpose of receiving radiation when using receivers with one or more radiation-sensitive pointed contacts the: impinging Directing radiation to punctiform locations of the receiver is according to the invention the metal wire having the contact tip immediately in front of its point of contact with the radiation-sensitive layer or in its vicinity by such a collecting layer optical system, which is carried only by the metal wire, passed through that the incident rays at a point at the point of contact of the contact tip be united.
Dieses optische System kann dem jeweiligen Gebrauchszwecke weitgehend .angepaßt werden und sowohl aus einem System optischer Linsen oder ,auch .aus einem .einzigen kugelförmigen oder fast kugelförmigen Vollkörper ,aus Glas oder einem anderen die auftreffende Strahlung möglichst wenig absorbierenden Stoff, z. B. Flußspat, Korund o. dgl., bestehen.This optical system can largely be used for the respective purpose .Adapted and both from a system of optical lenses or from one .single spherical or almost spherical solid body, made of glass or a other the incident radiation as little absorbing material as possible, z. B. fluorspar, Corundum or the like., Exist.
Durch die geschilderten Vorkehrungen bei punktförmigen Strahlungsempfängern mit strahlungsempfindlichem Spitzkontakt ist der Vorteil einer einfachen 'und gedrängten Anordnung mit einer wesentlichen Steigerung der Lichtempfindlichkeit und damit verbunden einer erheblichen Verstärkung der Empfangsspannung verknüpft. Wird der Strahlungssammler mit Hilfe einer Feder noch besondert gehaltert, so ist er dadurch verläßlich in seiner Lage gesichert.By taking the precautions outlined for point radiation receivers with radiation-sensitive pointed contact is the advantage of a simple 'and compact Arrangement with a substantial increase in photosensitivity and associated therewith linked to a considerable gain in the received voltage. Will the radiation collector is specially held with the help of a spring, so it is thereby reliably secured in its position.
Die Zeichnung veranschaulicht zwei Ausführungsbeispiele des Gegenstandes nach der Erfindung.The drawing illustrates two embodiments of the subject according to the invention.
Gemäß Fig. i stellt i einen Strahlungsempfänger mit in einer strahlungsempfindlichen Schicht 2 eingefügtem, zu bestrahlenden Spitzkontakt 3 dar, der das Ende eines Metalldrahtes q bildet. 5 ist ein sammelndes optisches System aus einem die auftreffende Strahlung möglichst wenig absorbierenden Stoff, das die einfallende Strahlung nach der Spitze 3 des Metalldrahtes q. hin sammelt.According to FIG. I, i represents a radiation receiver with a radiation-sensitive one Layer 2 inserted, pointed contact 3 to be irradiated, the end of a metal wire q forms. 5 is a collecting optical system consisting of the incident radiation As little as possible absorbing material that the incident radiation towards the tip 3 of the metal wire q. collects.
In Fig. 2 ist der Strahlungssammler 5 als Kugel ausgebildet und in unmittelbarer Berührung mit der strahlungsempfindlichen Schicht 2. 3 ist wieder der strahlungsempfindliche Spitzkontakt. Auch bei dieser Darstellung trifft die Strahlung von oben her auf die Vorrichtung und wird durch den Strahlungssammler 5 nach der strahlungsempfindlichen Stelle, dem Spitzkontakt 3, hin konzentriert.In Fig. 2, the radiation collector 5 is designed as a sphere and in direct contact with the radiation-sensitive layer 2. 3 is again the radiation-sensitive pointed contact. In this representation, too, the Radiation hits the device from above and is passed through the radiation collector 5 concentrated towards the radiation-sensitive point, the pointed contact 3.
Die Einrichtung nach der Erfindung bietet ein wertvolles Hilfsmittel für den Telephonieempfang mit ultraxoten Strahlen, wobei vorwiegend der Strahlungsdetektor mit Spitzkontakt Verwendung findet. Durch die nach der Erfindung erzielte erhebliche Empfindlichkeitssteigerung des Empfängers neben einem einfachen und gedrängten Aufbau der Anordnitmg wird ein bequemes und schnelles Aufsuchen des Strahlungssenders ermöglicht.The device according to the invention offers a valuable tool for receiving telephony with ultra-exotic rays, predominantly the radiation detector with pointed contact is used. Due to the significant achieved according to the invention Increase in sensitivity of the receiver in addition to a simple and compact structure the arrangement enables a convenient and quick search for the radiation transmitter.
