摘要

围绕实际检验工作中遇到的问题, 以及国家推荐标准GB/T 10899-2009光学系统杂(散) 光测试方法中提出的要求, 论述了对光学系统全视场杂散光系数进行测试的必要性以及测量方法, 通过对现有杂散光测试装置的改造, 实现了对光学系统全视场杂散光系数的测试, 给出两种变焦距镜头全视场杂散光系数测试结果和分布状态曲线, 得到结论: 基本参数相近而型号不同的光学镜头, 其杂散光系数和分布状态会存在很大的区别。光学与机械结构形式不同是造成该区别的主要原因。测试数据能对光学系统杂散光抑制能力的提高起到参考作用。

Abstract

Aiming at the problems encountered in the actual inspection work and the requirements proposed in the GB/T 10899-2009 for test method of stray light in an optical system, we discussed the necessity for testing the stray light coefficient in the full field of an optical system and the corresponding methods of measurement. Through the transformation of the existing stray light testing device, we achieved the testing of stray light coefficient in the full field of an optical system, and gave the test results and distribution curves of stray light coefficient in the full field of 2 kinds of zoom lenses. It is concluded that there is a great difference in stray light coefficient and distribution between the lenses which have similar parameters but different models, and the different form of optical and mechanical structure is the main reason for this difference.The measurement data can offer a reference for improving the suppression ability of stray light in optic systems.
