| In this paper introduce zoom lens design, analyze the Gaussian optics and discuss the theory of zoom lens design. Then according as the design requests, calculate the parameters of lens, select the original configuration, and work out a25-150mm zoom lens, study the aberration theory, present the design result. The analysis of the Spot diagram and MTF (modulation transfer function) show that the zoom system can meet the requirement. In the end, research the cam’s curve of zoom lens, and present the zoom graph. |
