摘　　要：基于交叉非对称式切尔尼-特纳系统设计了一种宽光谱高分辨率微型分光系统,采用Zemax光学设计软件进行了光路设计、优化及像质分析后,得到了尺寸为70mm×42mm×15mm、波长范围为200~750nm、分辨率为1.5nm的分光系统,并搭建了实验光路对设计结果进行了性能验证,结果表明该系统满足了设计指标要求,具有小型化、高分辨率、结构简单、成本低等特点,可应用于水质在线自动分析仪器中进行多种水质参数的监测。A broad spectrum, high resolution micro spectral system is designed based on the asymmetric Czerny-Turner system. By utilizing Zemax, the opto-mechanical structure of the spectral system is thoroughly analyzed and optimized as well as the imaging performance of the system. A miniaturized spectral system with a wavelength range of 200 - 750 nm and a resolution of 1. 5 nm is realized within a 70 mm× 42mm × 15 mm cubic space. Experimental apparatus has been set up to verify the performance of the designed system. Test results suggest that the designed system meets all design requirements, and has advantages of miniaturized structure, high resolution, simple structure and low cost, which can be used in multi-parameter online water quality analysis.
