摘　　要：采用光学设计的基本原理,结合高光谱成像仪光学系统的特性,详细研究了宽光谱、长焦距衍/折混合光学系统消二级光谱的设计方法、步骤。按照消二级光谱的焦距分配公式,设计了消二级光谱的高光谱成像仪的衍-折混合光学系统,设计的光学系统满足实际使用要求,其二级光谱保持在设计水平以下(≤0.8mm)。Based on the optics design principle, according to the characteristics of High Spectrum Imaging Instrument （HSⅡ）, design method and steps for diffractive- refractive optical system of wide spectrum, long focus have been studied for correcting secondary spectrum. According to the formula of distributing focus for correcting secondary spectrum, a diffractive - refractive telescope system of HSⅡ was been designed to decrease secondary spectrum. The optical system is satisfied for actually use, the secondary spectrum is below of 0.8mm.
