摘要
从手持/便携式角度出发, 采用双光纤光路设计了激光拉曼测试装置中的探头, 并确定关键器件性能、型号及尺寸.利用Zemax软件进行光学模拟仿真, 得到入射光路的工作焦距为13.5 mm, 像方数值孔径为0.23; 收集光路的像面焦距为13.46 mm, 数值孔径为0.235.用SolidWorks软件进行机械设计, TracePro软件进行探头整体光路模拟, 通过计算机数字控制机加工和3D打印两种方式制作得到整体尺寸为50 mm×33.5 mm×17 mm的探头.用设计的拉曼探头对酒精样品进行了测试, 测得酒精拉曼光谱与商用产品测得的结果基本一致, 且在200~300 cm-1波数范围内有更好的信号表现.对K粉及冰毒进行了拉曼光谱测试, 实测数据与理论数据基本一致.实验结果表明拉曼探头的设计达到了预期效果, 并具有良好的性能.
Abstract
From the point view of handheld/portable scenario, a dual optical fiber path is adopted as Raman optical probe structure, and the performances, types and sizes of key components are determined. Optical simulation is carried out by Zemax software. The working focal length of the incident light path is 13.5 mm, the image square numerical aperture is 0.23, meanwhile the image plane focal length of the collected light path is 13.46 mm and the numerical aperture is 0.235. The whole optical path and relative structures of the probe are simulated by SolidWorks software and TracePro software. Finally, the probe shell with overall dimensions of 50 mm × 33.5 mm × 17 mm is fabricated by computer numerical control and 3D printing, respectively. The Raman spectrum of alcohol detected by the designed probe are almost the same as that by commonly used products on markets, and has better signal performance in the wave number range from 200 cm-1 to 300 cm-1. The Raman spectrum of drugs with methamphetamine components and K powder tested by the designed probe are in accordance with the theoretical data. The experimental results have proved the practicability of the designed handheld/portable probe.
