EMI2.2 Chromatisch und sphärisch korrigiertes Fernobjektiv aus einem positiven Glied langer und einem negativen Glied kurzer Brennweite, von denen jedes aus zwei verkitteten Linsen besteht und achromatisiert ist, dadurch gekonnzeichnet, dass die sphärische Abweichung nur für das Gesamtsystem korrigiert ist und das Positivglied eine höchstens dreimal und mindestens halb so grosse sphärische Uoterkorrektion besitzt wie eine einfache Sammel- EMI2.3 EMI2.4 EMI2.2 Chromatically and spherically corrected distance lens consisting of a positive element with a long focal length and a negative element with a short focal length, each of which consists of two cemented lenses and is achromatized, characterized in that the spherical deviation is only corrected for the entire system and the positive element is corrected a maximum of three times and at least spherical correction is half the size of a simple collective EMI2.3 EMI2.4
