| 中文摘要: |
| 为了同时满足光谱分辨率、光谱范围、探测器（CCD）上光谱信号覆盖区域要求，提出一种基于Czerny-Turner（CT）结构拉曼光谱仪的综合设计方法，通过Zemax软件采用逐步手动调节光栅倾斜，自动优化聚焦镜、柱面镜以及CCD间倾角和距离的方式，设计出全波段光谱分辨率优于4 cm-1，光谱波数范围为80~3 967 cm-1，光学结构尺寸为90 mm×130 mm×40 mm的微型拉曼光谱仪。 |

| In this paper,to simultaneously meet the requirements of the spectral resolution,spectral range and the spectrum signal coverage area on detector(CCD),we used Zemax to adjust the grating angle gradually and manually,optimize the focusing mirror,the cylindrical lens,the CCD angles and distances between all of them automatically.We proposed a comprehensive design method of Raman spectrometer,which is based on the Czerny-Turner(CT) structure,and successfully designed this micro-Raman spectrometer that owned the full-band spectral resolution better than 4 cm-1,wave number spectral range of 80~3 967 cm-1and the optical structure size of 90 mm×130 mm×40 mm. |
