Tr anspar ent skala für Lichtzeiger-InstrumenteTransparent scale for light pointer instruments
Die Neuerung bezieht sich auf ein .Anzeigegerät, bei dem mit Hilfe eines optischen Linsensystems ein Lichtzeiger auf die Rückseite einer transparenten Skala projeziert wird«, The innovation relates to a display device in which a light pointer is projected onto the back of a transparent scale with the help of an optical lens system, "
ist bekannt, als Werkstoff für die Skala Klar scheiben (Glas oder glaskare Kunststoffe) zu verwenden, die auf einer Seite mattiert sind (sogen= Mattscheiben)« Alle auf diese Art hergestellten Skalen weisen jedoch einen starken Helligkeitsabfall auf, wenn die Blickrichtung des Betrachters nicht mit der Richtung des von ρ der Lichtmarke ausgehenden Strahlenbündels zusammenfällt„ is known to use clear disks (glass or transparent plastics) as material for the scale, which are matted on one side (so-called = matt disks). “However, all scales produced in this way show a sharp drop in brightness when the viewer is not looking coincides with the direction of the beam emanating from ρ the light mark "
Die Neuerung löst die Aufgabe der Vermeidung eines Helligkeitsabfalles bei schräger Betrachtung der Skala eines Lichtzeiger-Instrumentes dadurch* daß zur Erzielung einer auch bei schräger Blickrichtung gleichmäßig hellen und scharfen Abbildung des Lichtzeigers auf der Skala auf den aus Glas oder einem glasähnlicheii Kunststoff bestehenden !Präger der Skala ? eine bis zu O5A eis dicke licht ζ erstreuende Schicht aufgebracht wirdo The innovation solves the problem of avoiding a decrease in brightness when viewing the scale of a light pointer instrument at an angle by * to achieve a uniformly bright and sharp image of the light pointer on the scale on the glass or glass-like plastic, which is made of glass or a glass-like plastic, to achieve an evenly bright and sharp image of the light pointer on the scale Scale ? a light ζ scattering layer up to O 5 A ice thick is applied o
Die Erfahrung hat gezeigt* daß es vorteilhaft ist, die zerstreuende Schicht nicht dicker als 0,,4 mm zu wählen. Da eine derartig dünne Skala den mechanischen Beanspruchungen, die beim !Transport und Gebrauch des Instrumentes auftreten können, nicht standhalten würdes ist die zerstreuende Schicht auf eine? Klarglasträger aufgebracht C Experience has shown * that it is advantageous not to choose a diffusing layer thicker than 0.4 mm. Since such a thin scale would not withstand the mechanical stresses that can occur during transport and use of the instrument, the dispersive layer is on a ? Clear glass carrier applied C
Ein Ausführungsbeispiel der Heuerung ist in der Figur dargestellte Mit T ist ein Klarglasträger bezeichnet, auf dem die ζ er-An embodiment of the hay is shown in the figure. With T is a clear glass carrier on which the ζ er
