Abstract

A general method for the calculation of paraxial design parameters of a double-sided telecentric zoom lens system with three components is given. Formulas that define the interval distances between components while zooming, the extremum of magnification, and the magnification of each component are derived. The kinetic property of the zoom system is also discussed. As a result of the study, a classification of three-component double-sided telecentric zoom lenses is given, which is based on the magnification, signs of component optical power, and the position of stop while zooming. Some numerical examples are given in the third section of the paper.
