摘要

摘要: 高精度光谱可调定标光源系统是针对高光谱遥感器的高精度定标提出的一种新型参考光源，设计了一个折射式宽谱段大相对孔径的准直物镜。镜头工作在400 nm~1 000 nm波段，半视场角2.2、相对孔径F/2.8、焦距135 mm。利用部分色散（P）和阿贝数（）的修正公式，基于复消像差的基本原理，获得了镜头的初始结构。借助Zemax光学设计软件进行优化设计，点校正了系统的二级光谱。最后，在设计波段上实现了复消色差，二级光谱残余量约为0.04 mm，其他像差也得到了良好的平衡。镜头的MTFs在37 lp/mm空间频率处均大于0.8，镜头整体性能满足设计指标。

Abstract: High accuracy spectral tunable calibration light source is a novel calibration light source, which especially accounts for the stringent calibration requirements of hyper-spectral remote sensors. A broadband and large aperture apochromatic collimator was designed. The lens worked in band of 400~1 000 nm, half field of view was 2.2, relative aperture F was 2.8, and focal length was 135 mm. According to the corrected formula of parial dispersion (P) and Abbe number (), the original optical structure was acquired, based on the principles of apochromatic lens design. The secondary spectrum was corrected well with the help of Zemax software. At last, the lens was apochromatic in the whole working band with secondary spectrum residual of about 0.04 mm, and other aberrations are balanced well. The Lens's MTFs are better than 0.8 at spatial frequency of 37 lp/mm, which meet the requirements of the light source system.
