摘　　要：针对宽波段Czerny-Turner结构像散校正存在的问题,分析了影响光学系统像散校正的主要因素。以工作波段为200~1000nm、全波段分辨率不低于2nm为初始光学参数,推导出交叉型Czerny-Turner结构光谱仪的一阶消像散条件,并结合零阶和一阶消像散条件以及消慧差条件搭建了Czerny-Turner结构。最后利用ZEMAX软件对初始结构进行了进一步仿真和优化,并设计出一个简易的外壳对该结构的可靠性进行了测试。Aiming at the astigmatism correction of wide-band Czerny-Turner structure,it analyzes the main factors affecting the astigmatism correction of optical system.It deduces the first-order astigmatism condition of the cross-type Czerny-Turner structure spectrometer with the initial optical parameters of 200~1000 nm working band and the resolution of the whole band not less than 2 nm,combines the zero-order and first-order astigmatism conditions and the elimination of the coma aberration conditions to establish the C-T structure,uses ZEMAX software to further simulate and optimize the initial structure,and designs a simple shell to test the reliability of the structure.
