Description

Die Erfindung bezieht sich auf Objektive mit zwei dreilinsigen positiven Wirkungsgruppen und einer auf diese folgenden Streulinse, die vor einer sich als Planscheibe auswirkenden elektronischen Bildröhre angeordnet ist und eine im Abstand vor der ersten Wirkungsgruppe liegende Blendenebene aufweist.The invention relates to lenses with two three-lens positive action groups and one to this following divergent lens, the one in front of an electronic picture tube acting as a faceplate is arranged and has a diaphragm plane located at a distance in front of the first action group.

Aus der deutschen Patentschrift 11 77 842 ist ein Objektiv bekannt, das in Tandemanordnung zur Übertragung eines Bildes von einer elektronischen Bildröhre auf eine elektronische Aufnahmeröhre dieni.From the German patent 11 77 842 is a Objectively known that in tandem for the transmission of an image from an electronic Picture tube on an electronic recording tube.

Dieses Objektiv ist wegen seiner zahlreichen kurzen Radien und seiner teuren Glassorten aufwendig in der Herstellung und es läßt in Tandemanordnung keine vignettierungsfreie Bildübertragung zu.This lens is expensive because of its numerous short radii and the expensive types of glass Production and it does not allow any vignetting-free image transmission in tandem.

Aufgabe der Erfindung ist es fertigungsmäßig problemlose Objektive zu schaffen, die in Tandemanordnung eine für die Übertragung eines Bildes vor einer elektronischen Bildröhre auf eine elekironische Aulnahmeröhre gute Abbildungsleistung ergeben.The object of the invention is to create lenses which are problem-free in terms of manufacture and which are arranged in tandem one for the transmission of an image in front of an electronic picture tube to an electronic recording tube result in good imaging performance.

Diese Aufgabe wird erfindungsgemäß durch Objektive der im Kennzeichen der Ansprüche 1 —3 beschriebenen Art gelöst.According to the invention, this object is achieved by lenses as described in the characterizing part of claims 1-3 Kind of solved.

In Tandemanordnung von zwei erfindungsgemäßen Objektiven können entsprechend dem jeweils erforderlichen Abbildungsmaßstab und den räumlichen Bedingungen Objektive unterschiedlicher Brennweite sowie unterschiedlichen Abstandes dei Blendenebene von der ersten Linse des Objektives vorgesehen sein.In a tandem arrangement of two lenses according to the invention can according to the required Image scale and spatial conditions lenses of different focal lengths as well different distance dei diaphragm plane can be provided from the first lens of the objective.

Es ist möglich, die beiden Objektive so anzuordnen, daß ein gewisser Abstand zwischen ihren Blendenebenen verbleibt, es muß dann jedoch eine geringfügige Vignettierung in Kauf genommen werden.It is possible to arrange the two lenses so that a certain distance between their diaphragm planes remains, but then a slight vignetting must be accepted.

Erfindungsgemäße Objektive ergaben ein vignettierungsfreies Bild großer Helligkeit bei praktisch ίο vollständiger Bildfeldebnung.Lenses according to the invention gave a vignetting-free image of great brightness with practically ίο complete image field flattening.

Die erfindungsgemäß ausgebildeten Objektive können in Tandemanordnung auch abgeblendet werden, ohne daß sich eine Vignettierung oder sonstige Beeinträchtigung der optischen Leistungen ergibt.
Im Rahmen der Erfindung sind gewisse Abweichungen von den in den Zahlentabellen angegebenen Werten möglich, soweit hierdurch die optischen Leistungswerte der Objektive nicht wesentlich beeinflußt werden.The lenses designed according to the invention can also be dimmed in a tandem arrangement without vignetting or any other impairment of the optical performance.
Within the scope of the invention, certain deviations from the values given in the tables of numbers are possible, provided that this does not significantly affect the optical performance values of the objectives.
