PATENT-ANSPRUCH : Sphärisch, chromatisch und astigmatisch korrigiertes Objektiv aus vier Linsen, von denen zwei durch eine sammelnde Kittfläche miteinander vereinigt sind. während die andern, die beide auf derselben Seite der verkitteten Linsen angeordnet sind, und von denen die aussenstehende eine aus Kronglas bestehende Sammellinse und die innenliegende eine Zerstreuungslinse ist, Luftabstand von einander haben und ein Nachbarflächenpaar mit negativem Stärkenvorzeichen bilden, dadurch gekennzeichnet, dass die alleinstehende Sammellinse aus einem Glas besteht, dessen Brechungsexponent für Natriumlicht kleiner oder höchstens gleich I'57 ist. PATENT CLAIM: Spherically, chromatically and astigmatically corrected objective consisting of four lenses, two of which are united by a converging cement surface. while the others, which are both arranged on the same side of the cemented lenses, and of which the outer one is a converging lens made of crown glass and the inner one is a diverging lens, have an air gap from one another and form a pair of neighboring surfaces with a negative strength sign, characterized in that the single one The converging lens consists of a glass whose refraction exponent for sodium light is less than or at most equal to I'57.
