一、前言随着照相物镜的设计和评价技术的发展,对透镜设计的要求日益增多。透镜不但要有高性能,还要具备良好的特性。另外,在设计的时候还要同时考虑批量生产的可能性以及减少幻象和杂光的产生等问题,而这些问题在以前的设计中是不予考虑的。这些问题中,设计能否顺利转向生产的透镜是一个较大的课题。解决这个课题的方法之一, I. Introduction With the development of photographic lens design and evaluation techniques, the requirements for lens designs are increasing. The lens not only has high performance, but also has good characteristics. In addition, the design should also consider the possibility of mass production and reduce the illusion and stray light and other issues, and these problems in the previous design is not considered. Among these problems, the design of the smooth transition to the production of the lens is a larger issue. One of the ways to solve this problem,
