用2种光学设计软件对像差特性进行的研究

Research of Aberration characterization using two different optical design softwares

  • 摘要: 目前用于光学设计的计算机辅助设计有许多种,但它们在像差特性参数的形式和表示方法上不尽相同,特别是国内外软件的这种差别更为明显,例如:ZEMAX将球差表示为“Longitudinal aberration”(纵向像差),其表示形式也与国内软件不同。另外,有些像差参数需要转换。采用美国焦点软件公司开发的光学设计软件ZEMAX和国内北京理工大学编写的DOS版CAOD对同一双胶合透镜进行光路计算,同时对其轴上球差、彗差、场曲和畸变等主要几何像差在2个软件之间的差别进行比较,以建立国内软件与国外软件在进行光学镜头设计时的光学像差特性参数的转换关系,并为光学设计者提供设计一种镜头或光学系统时使用不同的软件进行数据核查和复算的方法。

     

    Abstract: There are many optical design softwares, but they are different in forms and expression ways for aberration characteristics, especially between domestic and overseas softwares. The difference is very obvious, for example, the sphere aberration is called “longitudinal aberration”in ZEMAX developed by USA Focus Software Company, but there are some other expressions for it in domestic software including CAOD developed by Beijing Science Technology University, and some other aberration parameters still need to be transferred. In this paper, the beam path of the same cemented double lens was calculated by both ZEMAX and CAOD optical design softwares, and their calculation results of axile aberration, comatic aberration, field curvature, distortion were compared. The purpose of comparison is to build the transforming relationship between the parameters of optical aberration characteristics for the domestic and overseas softwares, and is to provide the way for optical designers to check and recalculate the data with different softwares during designing a lens or optical system.
