The crossing czerny - tumer structure used by the optical system is analyzed . the ray tracing and aberration analysis of the spectrometer is realized with autocad and oslo . the quality of spectral images is also evaluated by oslo to get the optical configuration within aberration limits 对光学系统所采用的交叉光路czerny - turner结构进行了分析，使用autocad和oslo软件对光学系统进行了追迹和像差分析，并利用软件对光谱成像质量进行了评价，得到满足几何像差容限要求的光学结构。
