anastigmatischer Bildfeldeb-1. Mikroskopobjektiv mit geebnetem Bildfeld, welches ein nach der Seite der längeren Strahlenweite zu meniskenförmig durchgebogenes Linsenglied G enthält, welches bei einer axialen Dicke grösser als 0, 8 F und kleiner als 6 F. aus zwei oder mehreren Einzellinsen zusammengesetzt ist und objektseits von welchem, das ist nach der Seite der kürzeren Strahlenweite, mehrere vorzugsweise sammelnde Linsenglieder angeordnet sind, dadurch gekennzeichnet, dass die dem Objekt zugekehrte Höhlung des erwähn - ten meniskenförmigen Linsengliedes einen Krümmungsradius aufweist,
welcher gleich oder grösser ist als derjenige der benachbarten Linsenfläche des vorangehenden Linsengliedes und dass auf das meniskenförmige Linsenglied G in einem grösseren Abstand wenigstens ein ebenfalls nach dem Bild zu durchgebogenes Linsenglied mit zerstreuender Brechkraft folgt mit einem Krümmungsradius an der Hohlfläche,

EMI5.2
anastigmatic field of vieweb-1. Microscope objective with a flattened field of view, which contains a lens element G which is bent into meniscus-like shape towards the side of the longer beam width, which, with an axial thickness greater than 0.8 F and less than 6 F., is composed of two or more individual lenses and on the object side of which, the is on the side of the shorter beam distance, several preferably converging lens elements are arranged, characterized in that the object facing cavity of the meniscus-shaped lens element has a radius of curvature,
which is equal to or greater than that of the adjacent lens surface of the preceding lens element and that the meniscus-shaped lens element G is followed at a greater distance by at least one lens element with a diffusing refractive power, which is also bent towards the image and has a radius of curvature at the hollow surface,
