Classical optical systems with variable optical characteristics are composed of several optical elements that can be moved with respect to each other. The mechanical change of position of individual elements (or group of elements) then enables to achieve desired optical properties of these optical systems e.g. the range of focal length or magnification. The disadvantage of such systems is that individual elements of these optical systems have to move very precisely along calculated trajectories, which results in high requirements on mechanical construction of such systems. Therefore it would be advantageous to be able to build optical systems without moving parts that would have the same (or similar) properties as above mentioned classical zoom systems. Nowadays, there exist several types of tunable lenses with a variable focal length based on different principles. This fact makes possible to perform the analysis of zoom optical systems based on variable power lenses. Our work deals with the analysis of possible designs of zoom optical systems using such lenses.
