Abstract
The method of calculating a new structural model of a lens with a variable focal length is presented. The main composition is represented by three components, two of which are movable. The schemes of the lens with mechanical and optical compensation of an image are examined. It was found that the composition with a movable first component provides small sizes. On the basis of the proposed formula the parameters of the composition with a movable first component providing a small size and given the design parameters of a zoom lens of three components and the discrete-type lens with ten-fold magnification. Mathematical models prove that there are two and four potential solutions to the infinite and finite conjugate systems, respectively, and all roots can be obtained by simple algebraic calculations.
