中倍消色差物镜设计
摘要
本课程设计侧重于使用ZEMAX软件设计消色差显微镜物镜。ZEMAX是一款用于模拟, 分析和协助光学系统设计的软件。它的界面很容易使用,并且可以通过一些练习来实现 交互式设计。这次设计的物镜由两个双层胶合组成。每aging of the object mirror by the object mirror, so how to measure the quality of a microscope, the optical technical parameters of the object mirror are the most important. The most important criteria that directly affect image quality. The object lens is made up of a set of separate distances and fixed, a group of or multiple groups of glued lenses, in order to correct aberrations and aberration are many specific requirements for the objective lens, such as the axis or focus of the lens group, so the structure of the objective lens is very complex and requires precise manufacturing process. Because the numerical aperture of the modern object lens (a very important reference data of the object mirror) is close to the limit, the resolution of the field center of the object lens imaging is almost no different from the theoretical value of the research, which means that the modern microscopes have reached a highly perfect ground step, so the edge of the field of view is meticulous and apparent. The enlargement of the field has become our current research work. The main purpose of this lesson is to design an optical system for 40 x microscope objective lens. In order to design a relatively complete lens optical system, the imaging spot (that is, error) can reach the diffraction limit and can solve the system aberration perfectly. The main application optical design software is ZEMAX, and then we will introduce the history and function of ZEMAX in process of designing optical lens optical system is a process of repeated optimization. It needs to be optimized by computer initial optimization, system analysis, computer adjusting parameters, changing parameter variables, and optimizing again. Finally, by analyzing the important parameters such as the mean square deviation of wave front and the mean square variance of wave image,
