摘　　要：介绍了大口径、宽光谱、折射式平行光管物镜的设计理论。结合项目设计实例：工作波长范围400-1100nm，焦距2000mm，相对口径1／10的折射式平行光管系统，论述了光学设计初期玻璃材料选取、初始结构选取与光焦度分配等问题。利用修正的相对部分色散P与阿贝数y建立复消色差方程组求解初始结构，使用Zemax软件优化设计出在全谱段范围内复消色差的平行光管系统。最后，给出Zemax软件分析的像差结果，系统中心视场内的点列图优于5μm，中心波长波像差优于1／60λ，焦距色偏移量为0．33mm，其余像差均在设计指标之内。The design theory of large aperture and wide spectrum refracting collimator was introduced. The refracting collimator system of the suitable glass materials, original configuration selection, and power allocation was discussed with the wavelength range of 400 - 1100 nm, the focal length of 2000 mm and the relative aperture of 0.1. Based on the modified relative partial dispersion P and Abbe number V, the apochromatic equations was calculated to solve the initial structure, and then the final design was optimized in the whole spectral range by Zemax software. Finally, results show that the spot diagram is better than 5 μm within the center field of view, central wavelength of wavefront aberration is better than 1/60λ and the maximum focal shift range is less than 0.33 mm, and the remaining aberrations are well revised in the design index
