   Das neue Objektiv kann sowohl als Einzelobjektiv, wie auch als   Doppelobjoktiv   benutzt werden. Da   das     Einzelobjektiv komatisch korrigiert   ist, eignet sich dasselbe besonders als Satzobjektiv, d. h. als Objektiv, welches mit einem oder mehreren Objektiven gleicher Art von verschiedenen Brennweiten zu einem Satz vereinigt ist, zu dem Zwecke, durch Kombination verschiedener Objektive des Satzes miteinander eine Variation der Brennweiten der Objektivkombination zu erzielen.

   The new lens can be used both as a single lens and as a double lens. Since the individual lens is comatically corrected, it is particularly suitable as a set lens, i.e. H. as a lens, which is combined with one or more lenses of the same type of different focal lengths in a set, for the purpose of achieving a variation of the focal lengths of the lens combination by combining different lenses of the set with one another.

Claims

EMI2.2 Objective of four cemented lenses, characterized in that a central lens of any character, i.e. H. either diffusing or converging, is enclosed on one side by one and on the other side by two lenses of opposite character, the cemented surfaces on both sides of the central lens being of opposite character and the additional cemented surface being convergent and oppositely curved, like the second present in the system collecting putty surface.
