末组补偿变焦镜头设计
Design of Rear-Focus Zoom Lens
摘要
阐述了一种新型的末组补偿变焦镜头的设计方法。以最小偏折角为目标函数优化薄透镜系统,推导了便于编程的像差系数的矩阵形式,构建了基于点列弥散圆的目标函数对各薄透镜P,W参数进行优化,编写宏语言实现了薄透镜的实例化,最终得到变焦镜头的初始结构。充分结合了传统PW法获得有潜力初始结构的能力和现代优化算法强大高效的优点。依据给出的方法,得到了一个焦距为5~50 mm,F数为1.6,且具有优良成像质量的10倍末组补偿连续变焦镜头,证明了所述方法的优越性和实用性。
Abstract
The principle and method of designing rear-focus type zoom lens are presented. The main ideas include optical power determination of each lens group, P, W parameters optimization based on system aberrations balance, and getting the initial real lens groups. By this method, a rear-focus continuous zoom lens, with focal length of 5~50 mm, F-number of 1.6 and good image quality, is obtained. The effectiveness of the method is proved by this example.
