Description

Gebrauchsmuster Rolf Friderici Anmelder : Geräte für Licht-und Strahlungsmessung Berlin-Wilmersdorf, Fehrbelliner Platz 3 Bezeichnung : Lichtelektrischer Glanzmesser Die objektive Messung des Glanzes von Oberflächen mittels Photozellen derart durchzuführen, daß die Meßergebnisse mit dem visuellen Glanzeindruck übereinstimmen, ist die Aufgabe des Glanzmessers. Utility model Rolf Friderici Applicant: Devices for light and radiation measurement Berlin-Wilmersdorf, Fehrbelliner Platz 3 Description: Photoelectric gloss meter To carry out the objective measurement of the gloss of surfaces by means of photocells in such a way that The task is that the measurement results agree with the visual gloss impression of the glossmeter.

Seine Entwicklung geht auf Untersuchungen (1) zurück, die zeigten, daß die bisherigen Methoden der objektive Glanzmessung unzulänglich sind. Es wurde festgestellt, daß der Glanz einer Oberfläche nicht durch eine, sondern zwei Maßzahlen bestimmt wird, Spiegelwert und Bildschärfe. Der Spiegelwert ist der streng nach dem Reflexionsgesetz von der Probenoberfläche zurückgeworfene Lichtstrom (regulärer Strahl). Die Bildschärfe ist bestimmt durch den innerhalb eines Streukegels # zurückgeworfenen Lichtstrom. Der Scheitel des Streukegels liegt auf der Probenoberfläche, die Achse ist die Richtung des regulären Strahl.s Das neue Verfahren der Glanzmessung besteht darin, eine Analyse des Lichtstroms innerhalb des Streukegels derart auszuführen, daß Ergebnisse erhalten werden, die in Beziehung ZUG visuellen Glanzeindruck stehen.Its development goes back to studies (1) which showed that the previous methods of objective gloss measurement are inadequate. It was found that the gloss of a surface is not through one, but two dimensions is determined, mirror value and image sharpness. The mirror value is strictly according to Luminous flux reflected back from the sample surface according to the law of reflection (regular Beam). The image sharpness is determined by the amount reflected within a scattering cone # Luminous flux. The vertex of the scattering cone lies on the sample surface, the axis is the direction of the regular beam. The new method of gloss measurement exists in carrying out an analysis of the luminous flux within the scattering cone in such a way that that results are obtained which are related to visual gloss impression.

Hierzu wurde der lichtelektrische Glanzmesser entwickelt (Abb. 1). Das Licht der Beleuchtungslampe B wird durch die Linse 1 1 gesammelt, durch die Blende S 1 begrenzt und gerichtet unter dem Glanzwinkeld, auf die Probenoberfläche ? geworfen. Das reflektierte Licht gelangt in den Empfängertubus E. Das Lichtbündel wird gegebenenfalls durch die Blende S 2 begrenzt und durch die Linse L 2 so gerichtet, daß das Bild der Lampenwendel innerhalb der Ebene E der Blende S 3 liegt. Die Strahlen, die unter dem Winkel <S, gemessen gegen den regulären Strahl, von der Oberfläche reflektiert werden, treffen auf konzentrischen Kreisen auf E. Die notwendige Analyse kann auf zwei Wegen durchgeführt werden : 1. Die Blende S 3 ist eine Irisblende, hinter der sich eine Photozelle zur Messung der lichtintensität befindet. Gemessen wird die lichtintensität bei versohiedenen Öffnungen der Irisblende.The photoelectric gloss meter was developed for this purpose (Fig. 1). The light of the illumination lamp B is collected by the lens 1 1, through the Aperture S 1 limited and directed at the glancing angle on the sample surface ? thrown. The reflected light reaches the receiver tube E. The light beam is optionally limited by the diaphragm S 2 and directed through the lens L 2 so that that the image of the lamp filament lies within the plane E of the diaphragm S 3. The Rays, those at the angle <S, measured against the regular ray, from the surface be reflected, meet on concentric circles on E. The necessary analysis can be done in two ways: 1. The aperture S 3 is an iris diaphragm behind which there is a photocell for measuring the light intensity is located. The light intensity is measured at different openings of the iris diaphragm.

2. Die Blende S 3 ist eine oder mehrere Ring-oder Schlitzblenden, hinter denen sich eine oder mehrere Photozellen befinden, die die Lichtintensität in gewissen Intervallen von zu messen gestatten.2. The diaphragm S 3 is one or more ring or slit diaphragms, behind which there are one or more photocells that control the light intensity allow to measure at certain intervals of.

Die erhaltenen Meßergebnisse werden als Glanzkoordinaten 1 in ein Nomogramm eingetragen, das entsprechend dem unter 1 bzw. 2 beschriebenen Meßverfahren so berechnet wurde, daß Spiegelwert s und Bildschärfe b einer Oberfläche graphisch ermittelt werden können (Abb. 2). Die Bildscharfe iGt = 0% für eine absolut matte Oberfläche, = 100% für den ebenen Spiegel. 1) H. D. Schulz-Nethke :"Glanz und Glanzeindruck" Metalloberfläche A 8, 161 (1954) Anlagen : 2 Blatt Zeichnungen Schutzansprüche.The measurement results obtained are entered as gloss coordinates 1 in a nomogram, which was calculated according to the measurement method described under 1 or 2 so that the mirror value s and image sharpness b of a surface can be determined graphically (Fig. 2).
