Description

Strahltpgspyrometer mit Objektivlinse Die Erfindung- betrifft ein. Strahlungspyrometer mit Objektivlinse. Strahlungspyrometer, bei welchen das temperaturempfindliche Organ und die Skala im Gesichtsfelde des Okulars liegen, sind bekannt. Man hat auch schon vorgeschlagen, die Strahlung des zu untersuchenden Körpers zur Beleuchtung heranzuziehen, aber der Vorschlag enthält keine Angabe über die Art und Weise, wie die Skala beleuchtet werden soll. Die vorliegende Erfindung will nun die Beleuchtung der Skala dadurch bewirken, daß die Objektivlinse in einer durchsichtigen Fassung angeordnet ist, und zwar derart, daß ein Teil der Strahlen des Körpers, dessen Temperatur untersucht werden soll, ungebrochen zur Temperaturskala gelangt. Bei einer anderen Ausführungsform der Erfindung soll ein Teil der Strahlen durch parallel zur optischen Achse liegende spiegelnde Flächen bis zur Temperaturskala geleitet werden.Beam pyrometer with objective lens The invention relates to a. Radiation pyrometer with objective lens. Radiation pyrometers, in which the temperature-sensitive The organ and the scale in the field of view of the eyepiece are known. One also has already proposed, the radiation of the body to be examined for illumination to be used, but the proposal does not specify how the scale should be illuminated. The present invention is now about lighting the scale cause the objective lens in a transparent mount is arranged, in such a way that a part of the rays of the body, its temperature is to be examined, reaches the temperature scale unbroken. With another Embodiment of the invention seeks part of the rays through parallel to the optical Reflective surfaces lying on the axis can be guided up to the temperature scale.

In Abb. z und 2 ist die Ausführung dieses Gedankens veranschaulicht, und zwar beispielsweise bei einem Gesamtstrahlungsmesser, dessen Strahlungsempfänger aus einem Bimetallthermometer besteht. In einem zylindrischen Gehäuse G befindet sich in unmittelbarer Nähe des Brennpunktes der Objektivlinse E ein spiralförmiges Bimetallthermometer R mit dem Zeiger T, hinter welchem ein kleiner Spiegel S zur Verstärkung der Wärmewirkung in bekannter Weise angebracht ist. Zur Messung des jeweiligen Ausschlages des Zeigers T ist eine durchsichtige in Temperaturgrade eingeteilte Skala H vorhanden, welche in bekannter Weise im Gesichtsfeld des Okulars D liegt. Um während des Anvisierens des zu untersuchenden Strahlers die Skala H, und zwar an der Stelle, an welcher sich die Einteilung befindet (Abb. 2) zu beleuchten, ist die Objektivlinse E in einem konzentrischen Fenster C aus durchsichtigem Material gefaßt. Ein Teil der Ofenstrahlung A wird durch die Linse E gebrochen und auf der Bimetallspirale R vereinigt, während die übrigen Strahlen A1 durch das Fenster C ungebrochen durchtreten und die Skala H an der gewünschten Stelle beleuchten.In Fig. Z and 2 the implementation of this idea is illustrated, for example in the case of a total radiation meter, its radiation receiver consists of a bimetal thermometer. Located in a cylindrical housing G. In the immediate vicinity of the focal point of the objective lens E, a spiral shape Bimetal thermometer R with pointer T, behind which a small mirror S to the Reinforcement of the thermal effect is attached in a known manner. To measure the The respective deflection of the pointer T is a transparent one divided into temperature degrees Scale H is present, which lies in the field of view of the eyepiece D in a known manner. To read the scale H while aiming at the radiator to be examined, namely at the point where the division is located (Fig. 2) is to be illuminated the objective lens E in a concentric window C made of transparent material collected. Part of the furnace radiation A is refracted by the lens E and on the Bimetallic spiral R combined, while the remaining rays A1 through the window C Step through unbroken and illuminate the scale H at the desired point.

Um ein schärferes Lichtbild der strahlenden Fläche zu erreichen, ist es mitunter notwendig, die Randstrahlen der Objektivlinse abzublenden. In Abb. 3 und q. ist eine weitere Ausführungsform dargestellt, in welcher die Beleuchtungsvorrichtung, für die Skala mit einer Blende vereinigt ist. Zu diesem Zweck. ist in das Gehäuse G, welches im Innern zur besseren Reflektion der sichtbaren Strahlen eine spiegelnde Fläche besitzt, ein mit dem Gehäuse konzentrisches Rohr L eingefügt, welches auf seinem äußeren Umfange gleichfalls eine spiegelnde Fläche enthält. Ähnlich wie bei der vorigen Ausführung treten hier die Strahlen A durch die Objektivlinse E ein und werden auf dem Bimetallthermometer R konzentriert. - Die durch den Rand der Linse eintretenden Strahlen Ar gelangen hingegen nach mehrfacher Reflektion an den spiegelnden Flächen der Rohre L und G zur Skala H, welche sie an der geeigneten Stelle beleuchten. Bei Durchsicht durch das Okular D lassen sich dann die jeweiligen Ausschläge des Zeigers T in bequemer Weise beobachten.To achieve a sharper image of the radiating surface, is it is sometimes necessary to mask the marginal rays of the objective lens. In Fig. 3 and q. a further embodiment is shown in which the lighting device, for the scale is united with an aperture. To this end. is in the case G, which has a reflective inside for better reflection of the visible rays Has surface, a concentric tube L inserted with the housing, which on its outer circumference also contains a reflective surface. Similar to In the previous embodiment, the rays A enter through the objective lens E here and are concentrated on the bimetal thermometer R. - The one by the edge of the On the other hand, rays Ar entering the lens reach the after multiple reflection reflective surfaces of the tubes L and G to the scale H, which they at the appropriate Illuminate the spot. When looking through the eyepiece D, the respective Observe the deflections of the pointer T in a convenient manner.
