Description

Photographisches Objektiv vom modifizierten Gaußtyp Die Erfindung betrifft sechslinsige photographische Objektive vom modifizierten Gaußtyp, insbesondere solche, bei denen vor der Blende vier und hinter der Blende zwei Linsen angeordnet sind. Derartige Objek- tive sind bereits in der französischen Patentschrift 1374 796 beschrieben worden. Bei den dort offenbarten Objektiven sind für die Sammellinsen teilweise teuere Glasarten verwendet worden. Durch systematische Untersuchungen wurde ein Weg gefunden, bei Objektiven des hier behandelten Typs mit billigeren Glassorten einen nahezu gleichwertigen Korrektionszustand zu erzielen.Photographic lens of the modified Gaussian type The invention relates to six-lens photographic lenses of the modified Gaussian type, in particular those in which four lenses are arranged in front of the diaphragm and two lenses are arranged behind the diaphragm. Such objectivity tive have already been described in French Patent 1,374,796. In the lenses disclosed there, some expensive types of glass have been used for the converging lenses. By means of systematic investigations, a way was found to achieve an almost equivalent state of correction for lenses of the type dealt with here with cheaper types of glass.

Bei den Objektiven der unten angegebenen Datentabellen sind für die Sammellinsen relativ billige Glasarten verwendet worden.

Auch Objektive, deren Fertigungsdaten nicht genau mit den angegebenen Daten übereinstimmen, sondem nur in der Nähe dieser Daten liegen, können freilich einen etwa gleichen Korrektionszustand aufweisen. Es empfiehlt sich aber, so dicht bei den angegebenen Daten zu bleiben, daß keine der Brechkräfte (A nIr) dem Betrag nach um mehr als 0,40 - llf und keiner der Scheitelabstände (d) dem Betrag nach um mehr als 0,04 - f von dem betreffenden in der Tabelle angegebenen Wert abweicht.Even lenses whose production data do not exactly match the specified data, but are only close to this data, can of course have approximately the same correction status. However, it is advisable to stay so close to the specified data that none of the refractive powers (A nIr) by more than 0.40 - llf and none of the vertex distances (d) by more than 0.04 - f deviates from the relevant value given in the table.
