Description

Photographisches Objektiv Die Erfindung betrifft Photoobjektive, welche aus 5 Gliedern bestehen und zwar im Sinne der Lichtrichtung einem meniskenförmigen, zur Blende hohl gekrümmten Zerstreuungsgliede, einem Sammelgliede, bei welchem die Radien der beiden Außenflächen dem Betrage nach länger sind als 0, 50'f, einem bikonvexen Sammelgliede, bei welchem die algebraische Summe der Flächenbrechkräfte (A n/r) in den Grenzen von 1,00'1/f und 2,00'1/f liegt, einem bikonkaven Zerstreuungsgliede und einem unsymmetrischen Sammelgliede, welches die stärker gekrümmte Fläche dem Bilde zukehrt.Photographic objective The invention relates to photographic objectives which consist of 5 members, namely in the sense of the direction of light a meniscus-shaped diffusion member hollowed towards the diaphragm, a collecting member in which the radii of the both outer surfaces are longer in amount as 0, 50'f, a biconvex collecting member, in which the algebraic sum of the surface powers (A n / r) lies within the limits of 1.00'1 / f and 2.00'1 / f, a biconcave dispersing member and an asymmetrical collecting member, which faces the image with the more curved surface.

Die Erfindung besteht in einer besonderen Modifikation dieses an sich bekannten Objektivtyps. Es wurde nämlich durch Untersuchungen gefunden, daß sich ein guter Kompromiß zwischen den einzelnen Aberrationen erzielen läßt, wenn man das dritte Glied so durchbiegt, daß seine dem vierten Gliede zugekehrte Außenfläche einen Radius innerhalb der Grenzen-3,00'f und-0, 50'f erhält.The invention consists in a particular modification of this per se known lens type. Namely, it has been found through research that a good compromise between the individual aberrations can be achieved if one the third link bends so that its outer surface facing the fourth link has a radius within the limits -3.00'f and -0.50'f.

Im Hinblick auf die schiefen Büschel günstige Korrektionsmöglichkeiten ergeben dabei solche Objektive, bei denen die Baulänge innerhalb der Grenzen 1, 00#f und 3,00f liegt.Favorable correction options with regard to the crooked tufts result in such lenses where the overall length is within the limits 1, 00 # f and 3.00f.

Für die Korrektion der Verzeichnung ist es vorteilhaft, den Luftraum zwischen dem vierten und dem fünften Gliede kleiner zu machen als den Luftraum zwischen dem dritten und dem vierten Gliede.For the correction of the distortion it is advantageous to use the airspace between the fourth and the fifth link smaller than the air space between the third and fourth link.

Die Bildfeldebnung wird erleichtert, wenn man die Hittendicke des dritten Gliedes größer als 0, 10#f, aber kleiner als 0, 50#f macht.The flattening of the image field is made easier if the thickness of the makes the third term greater than 0, 10 # f, but less than 0, 50 # f.
