Paper Abstract

An optical design of 2X optical miniature zoom lens with liquid lens elements and optimization method: discrete lens groups shifts (DLGS) has been presented in this research. Two liquid elements are applied to minimize the overall length of zoom optics. Moreover, a compensative optimization method with assistance of Genetic Algorism is introduced in this research with a new concept of DLGS, which not only solve the complicated problem of liquid optics itself but also improve the performance of optics. Genetic algorithms (GA) written in CODE V plays the role at finding out the appropriate parameters such as curvatures, thicknesses, glass materials and etc. Besides, one table with great lens groups shifts by GA would be created to move the lens groups on the optimal positions of different zooms. As a result, the DLGS optimization method associated with the GA optimization improve the zoom lens performance averagely 40% better than traditional ones.
