ABSTRACT:
The invention relates to optics comprising adjustable optical elements and, if desired, lenses of fixed focal lens. By use of an appropriate controller for the adjustable optical elements, characteristics of the optics can be advantageously varied. For this purpose, systems are provided which are suitable for use as surgical stereo-microscope, objective, ocular or zoom. A zoomable imaging optics comprises lenses and of variable optical power, which are oppositely controlled by means of a controller to change an imaging ratio, so that the optical power of the one lens is increased and the optical power of the other lens is decreased. Moreover, the imaging optics may comprise still further assemblies of fixed optical power.
