Abstract
This paper proposes a new zoom lens design with intermediate image. The two 3x zoom lenses are independently designed and then cascaded to a 9x zoom lens. The concept of intermediate optics is applied in this paper in order to minimize size of front diameter and overall length. The final layout shows the proposed 9x zoom lens can effectively miniature the front diameter of lens about 44.25%.
