Paper Abstract

This paper presents a paraxial study of a double-sided telecentric zoom lens system with four components in terms of matrix method and Gaussian brackets. Compared with a double-sided telecentric zoom lens system with three components, the four-component type is capable of achieving a large zoom range and the requirements for lens components can be easily fulfilled. As a result of the study, a classification of double-sided telecentric zoom lenses with four components is given and eight types of zoom lens systems are derived. The equations are prudently derived, and a method for solving the problem is explicitly provided for each type. Some numerical examples are also appended for most lens types.
