Latest Patents
Cai's latest patents include innovative designs for zoom lenses. One of his patents describes a zoom lens that consists of a first lens group, a second lens group, and a third lens group. The first lens group is positioned between the object side and the image side and features at least one aspheric surface. The second lens group possesses a positive refractive power and is situated between the first lens group and the image side. The third lens group, also with positive refractive power, is located between the second lens group and the image side and is designed to move relative to the second lens group for focusing.
Another patent by Cai presents a more complex zoom lens configuration. This design includes four lens groups arranged in sequence from the object side to the image side, with varying refractive powers: positive, negative, positive, and positive. The first lens group comprises a first and a second lens, while the second lens group includes a third, fourth, and fifth lens. The third lens group contains a sixth lens, and the fourth group consists of a seventh, eighth, and ninth lens. Each lens in this arrangement has specific refractive powers, contributing to the overall functionality of the zoom lens.
