Description

Photographisches Objektiv Die Erfindung betrifft photographische Objektive an sich bekannter Bauart, die aus einem meniskenförmigen sammelnden Vorderglied, einem bikonkaven zerstreuenden zweiten Glied und einem sammelnden dritten Glied bestehen, wobei dieses dritte Glied seinerseits aus zwei über eine zum zweiten Glied erhabene Verbundfläche miteinander verkitteten Linsen entgegengesetzter Brechkraft besteht.Photographic Lens This invention relates to photographic lenses known design, consisting of a meniscus-shaped collecting fore limb, a biconcave dispersing second link and a collecting third link consist, this third link in turn from two via one to the second link raised composite surface cemented together lenses of opposite refractive power consists.

Aufgabe der Erfindung ist es, Objektive der genannten Bauart zu entwickeln, die mit der kurzen Brennweite von etwa f = 25 mm als Standardobjektive für Kammern des Bildformates 12 - 17 mm verwendet werden können, eine Offnung von f : 2,8 besitzen und für einen Bildwinkel von etwa :E 25' korrigiert sind, derart, daß sich ein guter Kompromiß zwischen den einzelnen für die Bildgüte maßgebenden Aberrationen erzielen läßt. Die Ob- jektive sind so aufgebaut, daß sie sich folgenden zum Teil an sich bekannten Bedingungen gemeinsam unterordnen lassen: a) 0,36 - f < r, < 0,50 - f b) 4,00 - f < r2 < 15,00 - f c) 0,82 -.f < -r3 < 1,15 -f d) 0,42 - f < r6 < 0,70 - f e) 0,94 - f < r, -r7 < 1,20 - f f# Ö,40 < d2+ d4 <0,70 d, + d3 + d5 TW6 g) 0,65 < d2 < 0,85 d4 h) 0,35 - f < d, + d2 + d3 + d4+ d_, + d, < 0,50 - f Die unten angegebenen Tabellen enthalten die Zahlenwerte für zwei Objektive gemäß der Erfindung. Diese Zahlenwerte sind auf die Brennweite als Einheit bezogen.The object of the invention is to develop objective of the mentioned type, which with the short focal length f of about = 25 mm as a standard lenses for chambers of the image format from 12 to 17 mm may be used, an aperture of f: have 2.8 and for a Image angles of about: E 25 'are corrected in such a way that a good compromise can be achieved between the individual aberrations which are decisive for the image quality. The objec- tive are constructed so that they can be partly following subordinate common conditions known per se: a) 0.36 - f < r, <0.50 - f b) 4.00 - f < r2 < 15.00 - f c) 0.82 -.f < -r3 < 1.15 -f d) 0.42 - f < r6 <0.70 - f e) 0.94 - f < r, -r7 < 1.20 - f f # Ö, 40 < d2 + d4 <0.70 d, + d3 + d5 TW6 g) 0.65 < d2 <0.85 d4 h) 0.35 - f < d, + d2 + d3 + d4 + d_, + d, < 0.50 - f The tables given below contain the numerical values for two objectives according to the invention. These numerical values are related to the focal length as a unit.

Der Linsenschnitt dieser Objektive ist in der Abbildung dargestellt. Die in den nachfolgenden Tabellen angegebenen Objektive haben die Offnung f: 2,8, sie sind korrigiert für einen Bildwinkel von ± 25'. Die Objektive sollen mit der Brennweite f = 25 mm gefertigt werden.The lens section of these lenses is shown in the picture. The objectives specified in the tables below have the aperture f: 2.8, they are corrected for an angle of view of ± 25 '. The lenses should be manufactured with a focal length of f = 25 mm.

Eine besonders gut ausgeglichene Korrektion läßt sich erzielen bei den innerhalb des Rahmens der Erfindung liegenden Objektiven, deren Konstruktionsdaten so dicht bei den der nachfolgenden Tabellen zu entnehmenden Werten liegen, daß keine der Flächenbrechkräfte (A nIr) dem Betrag nach um mehr als 0,05 - llf und keiner der Scheitelabstände (d) dem Betrag nach um mehr als 0,02 -f von dem betreffenden, in den Tabellen jeweils angegebenen Wert abweicht.
