摘要
分析光栅的集光效率和光谱分辨力的影响因素,给出光谱仪结构参数的估计方法,为光谱仪的设计提供参考。基于所提出的方法,设计一套双波段高分辨力光栅光谱仪。结果表明,实际光谱分辨力好于1.56×105,达到了技术指标要求。
The influence factor of the grating diffraction efficiency and spectral power are analyzed in this paper, and the estimation method of the fundamental parameter of the grating spectrometer is given, which provide a reference for the design of grating spectrometer. Based on the proposed method, a dual band high spectral resolution grating spectrometer of NVST is designed. The simulation result shows that the real spectral power is 1.56×105, meeting the requirements of technical target.
