短焦距变焦物镜设计
Design of a Short Focal-length Zoom System
摘要
介绍了机械补偿式三组元连续变焦系统设计方法;基于微分解析法,提出快速变焦法用于优化系统高斯初始结构,减小了外形尺寸.并设计了一焦距3.87 mm～19.35 mm,视场76.6°～17.71°可见光变系统.设计结果表明:该变焦系统较之同类专利设计结果,具有结构紧凑、视场大、像面稳定度高的优点.
Abstract
A method for initial zoom system design was proposed.The new optimized arithmetic was used for designing based on differential analytic expression method.The results showed that the length of the system could be reduced in this way.An example of three moving group elements and mechanic compensator type was given with configuration f′=3.87~19.35 mm,ω=76.6°~17.71°.
