摘要: An objective lens comprises a housing, an iris diaphragm and a plurality of lens groups. For focusing the objective lens while minimizing the variation of the image angle at least two lens groups are adapted to be moved relative to the housing. The one lens group is arranged in front of the iris diaphragm. The other lens group is arranged at least partially behind the iris diaphragm.
