Description
Vorrichtung zur quantitativen Bestimmung des Grads der Opaleszenz. Lichtintensitäten, auch solche farbigen Lichtes, also spektrale Intensitäten, mittels geeichter Rauchglas- oder farbiger Keile quantitativ zu ermitteln, ist bekannt. Opalisierende Flüssigkeiten hat man dagegen bisher nur in Stufen mittels Vergleiches., Suspensionen oder eines auswechselbaren Systems von Rauchglasplatten oder nephelometrisch messen können. Die letztgenannte Methode erfordert große Übung mit einen kostspieligen Instrument, die erstgenannte liefert nur recht ungenaue Ergebnisse. Man hat vorgeschlagen, die Intensität einer Opalesz.enz durch einen verschiebbaren Keil aus schwarzem Glase zu bestimmen, und zwar unter Benutzung eines einem Koiorimeter nachgebildeten Apparates, dessen Standardlösung durch den Keil ersetzt wurde. Dabei hat man jedoch dunkles Klarglas als Keil verwandt. Die Verwendung von dunklem Glase ist jedoch mit der erheblichen Unbequemlichkeit verknüpft, daß es längerer Übung bedarf, bis man lernt, die Trübung des einen Lichtfeldes in Kongruenz mit dem meist andersfarbig erscheinenden anderen Lichtfelde zu bringen. Infolgedessen werden die Messungen vielfach unzulässig große Fehler ergeben, und schließlich wird sogar ein und derselbe Beobachter bei Variationen der Intensität der Lichtquelle Ergebnisse erhalten, die nicht übereinstimmen.Device for the quantitative determination of the degree of opalescence. Light intensities, including those of colored light, i.e. spectral intensities, by means of It is known to quantitatively determine calibrated smoked glass or colored wedges. Opalescent liquids, on the other hand, have so far only been available in stages by means of comparison., Suspensions or an interchangeable system of smoked glass plates or nephelometric can measure. The latter method requires great practice with an expensive one Instrument, the former only provides rather imprecise results. It has been suggested the intensity of an opalescence through a sliding wedge of black glass to be determined using an apparatus simulated by a coiorimeter, whose standard solution was replaced by the wedge. But you have something dark Clear glass related as a wedge. However, the use of dark glass is with that considerable inconvenience associated with the fact that it takes longer practice to learn the cloudiness of one light field in congruence with the one that usually appears in a different color to bring other fields of light. As a result, the measurements are often inadmissible large errors result, and ultimately even one and the same observer will be involved Variations in the intensity of the light source will give results that do not match.
Erfindungsgemäß läßt sich die Opaleszenz quantitativ und fortlaufend bestimmen, indem man als Meßelement ähnlich wie bei der Messung von Lichtintensitäten einen verschiebbaren Keil aus Opalglas verwendet, dessen Verschiebung an einer Meßvorrichtung abgelesen wird; die Eichung des Keils kann nach irgendeiner der bekannten Methoden geschehen. Die Optik des neuen Meßapparates kann in Verbindung mit dem Keil auf alle die Arten ausgebildet werden, die bei den Messungen von Klarlicht üblich sind. Z. B. kann man eine Halbschattenoptik oder eine Polarisationseinrichtung nach K r ü ß usw. verwenden.According to the invention, the opalescence can be quantitative and continuous determine by acting as a measuring element similar to the measurement of light intensities a slidable wedge made of opal glass used, its displacement on a measuring device is read; calibration of the wedge can be by any of the known methods happen. The optics of the new measuring device can be used in conjunction with the wedge trained in all of the ways that are common in measurements of clear light. For example, penumbra optics or a polarization device according to K. Use r ü ß etc.
Ein Vorzug der neuen Vorrichtung besteht darin, daß man beim Opalglas- (Asbestglas-) Keil auf die Anwendung eines Kompensationsstückes aus weißem Klarglas verzichten kann, das sonst zur Beseitigung der Farbenzerstreuung erforderlich erscheint. Das bei der neuen Vorrichtung verwandte Opalglas, welches sehr kleine Körnchen enthält, die das Glas selbstopaleszierend machen, läßt spektrale Zerlegung des Lichtes in störendem Umfange nicht auftreten.One advantage of the new device is that the opal glass (Asbestos glass) wedge on the application of a compensation piece made of white clear glass can do without, which would otherwise appear necessary to eliminate the scattering of colors. The opal glass used in the new device, which contains very small grains, which make the glass self-opalescent, allows spectral decomposition of the light into disturbing extent do not occur.
