Abstract
The optical design of 350X zoom lens with Diffractive Optical Element (DOE) is demonstrated at the proposal. This lens is composed of front elements, a zoom motor group and a compensation group. The compensation group is specially designed to meet the further step motors under the control of DSP chips. Besides, location of DOE will be determined by HTGA (Hybrid Taguchi Genetic Algorism) for further elimination of chromatic aberration. The results show that regardless of whether chromatic aberration is axial or longitudinal, issues concerning the optical lens's DOE location could be determined and chromatic aberration could be significantly reduced.
