“…The image-side telecentric can also provide a uniform illumination which is also very important. There are some papers in which the authors systematically discuss the design of zoom lenses [1][2][3][4][5][6][7][8][9] and some specific papers on the design of double-sided telecentric zoom lenses [10][11][12][13], but there is not much systematic discussion on the design of double-sided telecentric zoom lenses. The aim of this work is to perform a systematic analysis of the paraxial design of double-sided telecentric zoom lenses.…”

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.

“…Novel configurations of zoom lenses were constantly proposed for different applications. [9][10][11][12] In the constant pursuit for zoom systems with high image quality, large zoom ratio, and compact size, complex design forms with multiple moving lens groups are now more and more often adopted. 13 The quality of such a zoom lens design depends to a great extent on the starting point, including a good Gaussian layout and appropriate choice of lens group structures.…”

An expert system is developed for the automatic generation of initial layouts for the design of zoom systems with multiple moving lens groups. The Gaussian parameters of the zoom system are optimized using the damped-least-squares method to achieve smooth zoom cam curves, with the f-number of each lens group in the zoom system constrained to a rational value. Then each lens group is selected automatically from a database according to its range of f-number, field of view, and magnification ratio as it is used in the zoom system. The lens group database is established from the results of analyzing thousands of zoom lens patents. Design examples are given, which show that the scheme is a practical approach to generate starting points for zoom lens design.
