title: Three-component double conjugate zoom lens system from tunable focus lenses.
abstract: A method for calculation of paraxial parameters of the double conjugate zoom lens is described. Such an optical system satisfies the requirement that the object, image, and pupil planes are fixed during the change of magnification. Formulas are derived for the calculation of parameters of a three-component double conjugate zoom lens system with tunable focus lenses, which enable us to calculate the optical power of individual optical components with respect to the transverse magnification. The main advantage of such an optical system is the possibility to achieve required zooming properties without any mechanical movement of individual components of the zoom lens.
