Ss ist ein subjektives Farbpyrometer bekannt, bei dein durch Farbvergleieh die Farbtenperatur und durch Heiligkeitevergleich die schwarze Temperatur gemessen wird.

Kessung, however, takes a certain amount of time and requires experienced operators.
Es ist bekannt, daß blanke Metalle bei steigendem Enissionswinkel eine immer stärker polarisierte Strahlung emittieren. Werden in Pyrometern, mit denen die Temperatur von blankem Metall bestimmt werden soll, optische Bauteile, wie Spiegel oder Glasplatten verv/cndet, so können diese u.U. eine Analysatorwirkung auf den in das Meßgerät eintretenden polarisierten Strahl ausüben und so fehlerhafte MeEergebnisse verursachen.It is known that bare metals emit more and more polarized radiation as the angle of emission increases emit. Are in pyrometers, with which the temperature of bare metal is to be determined, optical components, such as mirrors or glass plates, so they may have an analyzer effect on the polarized beam entering the measuring device and thus cause erroneous MEE results.
Ss besteht die Aufgabe, ein Pyrometer zur gleichzeitigen llessung der Parbtemperatur und der schwarzen Temperatur eines Strahlers zu schaffen, das schneller arbeitet und leichter zu bedienen ist, als die bekannten und bei den die ineßwertverfälschende Polarisation durch optische Teile innerhalb des Gerätes auf einen vernachlässigbaren Wert zurückgeführt ist.The task is to use a pyrometer for simultaneous Reading of the park temperature and the black temperature to create a spotlight that works faster and is easier to use than the known ones and with the the ineßwertverfälschende polarization by optical Parts within the device are reduced to a negligible value.
