Abstract
The invention is directed to a zoom device which is built up of several lenses wherein at least one parallel entry beam is changed with respect to its diameter. The exit beam has the same optical axis as the entry beam. The zoom device of the invention is assembled from several zoom systems. The optical axes of the lenses of the different zoom systems are arranged so as to be mutually parallel or at least in a fixed spatial relationship so that in a beam made up of many individual beams the defined diameter remains constant because of the axes of the outer individual beams.
