## Abstract

In this paper, we propose a new approach to automatically retrieve the first-order design of double-sided telecentric zoom systems with high efficiency based on Particle Swarm Optimization (PSO) algorithms. We transform the design problem to realize a zoom lens system with fixed positions of both the front focal point and the rear focal point during zooming. We demonstrate that the proposed algorithm is much more efficient than the Monte Carlo algorithm in designing zoom systems with two fixed foci as well as a given zoom ratio. Furthermore, a compact first-order design of three-component 4X zoom system with two fixed foci is proposed to show the high efficiency and great potential of our proposed algorithm in searching proper first-order configuration for complex optical systems.
