Die Erfindung bezieht sich auf symmetrische Objektive eines mäßigen öffnungsverhältnisses, die innerhalb eines Bildwinkels von 40 bis 45° innerhalb des sichtbaren Bereiches bei der Abbildung in wahrer Größe eine Bildleistung aufweisen, die nur durch die Beugung beeinträchtigt wird. Darüber hinaus muß bei den großen in Frage kommenden Baumaßstäben mit Brennweiten um 1 m der sekundäre Farblängsfehler derart reduziert werden, daß eine echte apochromatische Korrektion erforderlich ist, also die Schnittweiten für drei Farben streng einander gleich sind.The invention relates to symmetrical lenses with a moderate aperture ratio that are within an angle of view of 40 to 45 ° within the visible area in the image in true Size have an image performance that is only affected by diffraction. In addition, must for the large building scales in question with focal lengths of around 1 m, the secondary longitudinal color error are reduced in such a way that a real apochromatic correction is required, i.e. the back focal lengths for three colors are strictly equal to each other.
Ein Objektiv gemäß der Erfindung besteht aus zwei spiegelbildlich einander gleichen aus je drei Linsen verkitteten Menisken, die die Blende einschließen, und zwei das System beiderseits nach außen abschließenden meniskenartigen einzelnen Linsen.An objective according to the invention consists of two mirror-inverted images of three each Lenses cemented menisci that enclose the diaphragm and two of the system on either side of the outside final meniscus-like individual lenses.
Die Brechzahlen der drei zu einer Komponente verkitteten Linsen steigen erfindungsgemäß von der Blende nach außen in etwa gleiche Stufen um 0,2 an; die sphärischen Fehler erreichen ein Minimum, wenn diese Stufen um 0,1 herum liegen und wenn die mittlere der verkitteten Linsen unsymmetrisch bikonkav ist. Ihre Radien verhalten sich, abgesehen vom Vorzeichen, etwa wie 1:3 bis 1:6. Die krummere Seite dieser bikonkaven Streulinse, die aus einem Glas mit verminderter Dispersion im Blauen besteht, ist der Blende zugewandt.According to the invention, the refractive indices of the three lenses cemented into one component increase from that Fade in to the outside in approximately the same steps by 0.2; the spherical errors reach a minimum when these steps are around 0.1 and when the central one of the cemented lenses is asymmetrical biconcave. Apart from the sign, their radii behave roughly like 1: 3 to 1: 6. The crooked side of this one The biconcave divergent lens, which consists of a glass with reduced dispersion in the blue, is the Facing aperture.

Die freistehenden äußeren Einzellinsen sind meiiiskenförmig und haben eine nur schwache Brechkrafl, die positiv oder negativ sein kann und nicht über 30%. absolut genommen, der Brechkraft des ganzen Systems hinausgeht.The free-standing outer single lenses are meiiisken-shaped and have only a weak power to vomit, which can be positive or negative and not over 30%. taken absolutely, that goes beyond the power of the whole system.
Diese Linsen schwacher Brechkraft beeinflussen den restlichen Astigmatismus der schrägen Bündel in günstiger Weise.These low power lenses influence the remaining astigmatism of the oblique bundles in cheaper way.
In der folgenden Tabelle sind die Daten von zwei Beispielen gemäß der Erfindung für eine Brennweite/= 100 und ein Öffnungsverhältnis von 1:15 angegeben; die Figur zeigt einen Längsschnitt durch das zweite der Beispiele.The following table shows the data of two examples according to the invention for a focal length / = 100 and an aperture ratio of 1:15 indicated; the figure shows a longitudinal section through the second of the examples.
