Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung bezieht sich auf solche Raster, deren Öffnungen zur Erzielung eines gleichmäßigen gegenseitigen Abstandes sämtlicher Punkte des damit erhaltenen Negatives in drei sich unter 60° schneidenden Reihen angeordnet sind und besteht in der Herstellung solcher Raster aus nur zwei unter 60° gekreuzten Linienlagen von bestimmter Stärke.The invention relates to such grid, the openings to achieve a uniform mutual spacing of all points of the negative thus obtained in three are arranged at 60 ° intersecting rows and consists in the production of such Grid of only two line layers crossed at 60 ° and of a certain thickness.

Damit nämlich dabei die Reihen der erhaltenen rautenförmigen Öffnungen sowie der Punkte des Bildes deutlich als drei sich unter 60 ° schneidende Reihenlagen hervortreten, müssen die Linien beider Lagen ebenso breit oder breiter als ihre Zwischenräume sein, denn sonst ergeben sich nur, wie bei den bisher bekannten Rastern aus zwei unter irgend einem Winkel gekreuzten Linienanlagen, zwei unter dem gewählten Winkel erscheinende Reihenlagen der Punkte.In doing so, namely, the rows of diamond-shaped openings obtained as well as the Points of the picture emerge clearly as three rows intersecting at 60 °, the lines of both layers must be as wide or wider than the spaces between them, because otherwise, as with the previously known grids, they only result from two under any one Angle crossed line systems, two rows appearing at the selected angle the points.

Fig. ι zeigt einen Raster der bekannten Art mit kreisrunden Öffnungen α in drei sich unter 6o° schneidenden Reihenlagen,Fig. Ι shows a grid of the known type with circular openings α in three row positions intersecting at 60 °,

Fig. 2 veranschaulicht im oberen Teile einen an sich bekannten Raster aus zwei unter 6o° gekreuzten Linienlagen, im unteren Teile dagegen die Ausbildung des Rasters nach dieser Erfindung.Fig. 2 illustrates in the upper part a known grid of two under 60 ° crossed line layers, in the lower part, however, the formation of the grid according to this Invention.

Schon diese Darstellung in Fig. 2 läßt erkennen, daß in dem oberen Teile die Anordnung der entstehenden rautenförmigen Öffnungen α in drei Reihenlagen keineswegs hervortritt. Werden die Linien aber, wie im unteren Teile der Fig. 2 entsprechend gegen ihre Zwischenräume verstärkt, so sind die drei Reihenlagen auch bereits aus der Rasterstruktur kl-ar ersichtlich. Erst dann sind aber auch die Rasteröffnungen im Verhältnis zur gedeckten Rasterfläche genügend klein, um unabhängig von ihrer rautenförmigen Gestalt lediglich die Form der verwendeten Blendenöffnung in den Punkten des Negativs wiederzugeben. Da nun jede allseitig symmetrische Blendenform, wie sie für den angestrebten Zweck doch lediglich in Betracht kommt, der rautenförmigen Rasteröffnung umbeschrieben sein muß, so ist es klar, daß die gedeckten Zwischenräume der Rasteröffnungen genügend breit sein müssen, um die scharfe Widergabe des Blendenbildes hinter jedem Rasterloch zu ermöglichen.This illustration in FIG. 2 already shows that the arrangement of the diamond-shaped openings α in three rows in no way emerges in the upper part. If, however, the lines are correspondingly reinforced against their interspaces, as in the lower part of FIG. 2, the three row positions can also be clearly seen from the grid structure. Only then are the grid openings sufficiently small in relation to the covered grid area to only reproduce the shape of the aperture used in the points of the negative, regardless of their diamond shape. Since every diaphragm shape that is symmetrical on all sides, as it is only possible for the intended purpose, must be described around the diamond-shaped grid opening, it is clear that the covered spaces between the grid openings must be sufficiently wide to allow the clear reproduction of the diaphragm image behind each Allow grid hole.
