Description

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.

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.

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.

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.

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.

The drawing illustrates two embodiments of the subject according to the invention.

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, 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.

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.
