ABSTRACT:
The invention concerns an objective (1) for an observation device (10), whereby the objective comprises an objective-lens-system, which consists of a first optical subcomponent (11, 14) on the object side and a second, optical subcomponent (12, 15), whereby the second optical subcomponent (12, 15) is arranged at a distance (d2) to the first optical subcomponent (11, 14) on the optical axis of the objective, and one of the subcomponents (12, 14) possesses a positive refractive power and the other subcomponent (11, 15) possesses a negative refractive power, which is hereby characterized in that the objective (1) has a zooming device. In addition, the invention concerns a microscope, which contains such an objective. Finally, a method for adjusting an objective (1) of an observation device (10) is provided with the invention.
