 Index besteht aus dem   zugeschärften   Ende o einer kleinen Stellschraube 0, welche durch die Seitenwand des Rohres H durchgesteckt ist. Das äussere Ende des Rohres ist mit einem Schauloch P versehen, das durch einen abnehmbaren Stöpsel b verschliessbar ist, um das Einfallen des Lichtes durch das Rohr K zu verhindern, sobald von der Adjustierungseinrichtung kein Gebrauch gemacht wird. 



   Um die Feststellung des Rohres F2 in bezug auf das Rohr   F zu   ermöglichen, ist in die Hülse L mit Innengewinde eine mit Schraubengewinde versehene geschlitzte Büchse Q einschraubbar. Durch Einschrauben der Büchse in die Hülse wird letztere auf der Schiene   K   fest-

 ist und das Lager für das Rohr F1 bildet. 



   R ist ein Sack aus lichtundurchlässigem Stoff, beispielsweise Samt, mit nach innen gekehrtem Flor, welcher den Reflektor H und die anliegenden Rohre   F     F2 und/ {umschliesst,   so dass das Aussenlicht von dem Reflektor vollkommen abgeschlossen ist. 



   Das Innere der von den Lichtstrahlen durchquerten Rohre wird in gewöhnlicher Weise geschwärzt und mit Einrichtungen versehen, welche nicht parallele Strahlen auffangen. 



   PATENT-ANSPRÜCHE :
1.'Aus zwei Visierrohren mit gebrochener optischer Achse bestehende Vorrichtung zur Bestimmung der Intensität von Farben, dadurch gekennzeichnet, dass die in bekannter Weise durch Lenker mit den Schenkeln der Visierrohre verbundene   Führungsschiene   den Reflektor   trägt-,   so dass sich dieser selbsttätig in die Winkelhalbierende der beiden Schenkel einstellt.

 Index consists of the sharpened end o of a small adjusting screw 0, which is pushed through the side wall of the tube H. The outer end of the tube is provided with a viewing hole P which can be closed by a removable plug b in order to prevent the light from entering through the tube K as soon as the adjustment device is not used.



   In order to enable the pipe F2 to be fixed in relation to the pipe F, a slotted bushing Q provided with a screw thread can be screwed into the sleeve L with an internal thread. By screwing the bushing into the sleeve, the latter is fixed on the rail K-
 EMI2.1
 and forms the bearing for the pipe F1.



   R is a sack made of opaque material, for example velvet, with an inward facing pile, which encloses the reflector H and the adjacent tubes F F2 and / {so that the outside light is completely closed off from the reflector.



   The interior of the tubes traversed by the rays of light is usually blackened and provided with devices which intercept non-parallel rays.



   PATENT CLAIMS:
1. 'From two visor tubes with a broken optical axis device for determining the intensity of colors, characterized in that the guide rail connected in a known manner by handlebars to the legs of the visor tubes carries the reflector, so that it is automatically in the bisector of the adjusts both legs.
