基于OptiCentric中心偏测量仪的红外光学镜组装调方法

在红外光学镜组装调过程中会产生光学中心偏，且红外材料对可见光不透明，不能使用传统的可见光装调模式，从而成为红外镜组装调的难点。论文提出了基于德国TRIOPTIC公司的OptiCentric双光路中心偏测量仪的装调方案，详细介绍了无镜座定中法与镜座法以及非球面的装调方法，并对无镜座定中法与镜座法的优缺点进行分析；论文还指出使用OptiCentric中心偏测量仪在非球面定中时存在一定的局限性；最后使用光学传递函数测试仪对无镜座法和镜座法装调的镜头进行了测试。测试结果表明：使用中心偏测量仪装调的镜头能够满足技术指标要求。

Assembly and adjustment method of infrared optical lens group based on OptiCentric center-deviation measuring instrument

In the process of assembling and adjusting the infrared optical lens group, the optical center-deviation will occur. Since the infrared material is not transparent to visible light, the traditional visible light adjustment mode cannot be used, which becomes a difficulty in the assembly and adjustment of the infrared lens group. An assembly and adjustment scheme based on the OptiCentric dual-optical path center-deviation measuring instrument from TRIOPTIC company in Germany was proposed, and introduced in detail the assembly and adjustment methods of no-mirror seat centering method, the mirror seat method and the aspheric surface. The advantages and disadvantages of the no-mirror seat centering method and the mirror seat method were analyzed. In addition, it was pointed out that there were still some limitations in the centering of aspheric surfaces using the OptiCentric center-deviation measuring instrument. Finally, the optical transfer function tester was used to test the lens adjusted by the above two methods. The test results show that the lens adjusted by the center-deviation measuring instrument can meet the requirements of technical indicators.
