摘　　要：将衍射和折射光学元件结合,对星载用宽光谱(420.0～900.0nm)、长焦距(450mm)望远物镜的二级光谱进行了校正,计算了衍射透镜的结构尺寸和望远镜系统的像差。计算机模拟结果表明:采用衍/折射混合校正后的望远物镜的二级光谱不大于0.08mm,轴上点的位置色差也很小,实现了复消色差,光学传递函数也基本接近衍射极限。所设计的整个系统可以满足实用要求。The secondary spectrum of an aerospace wide spectrum (420.0～900.0 nm) and long focus (450 mm) telescope was corrected by combining diffractive and refractive optical elements, and the structural dimensions of diffractive lens and the aberrations of a telescope system were calculated as well. Computer simulation results showed that the secondary spectrum of the telescope objective lens corrected by combining diffractive and refractive optical elements was no greater than 0.08 mm, and the position aberration of a point on the axis was also very small, and repeated elimination of aberration was achieved. The optical transmission function was generally close to the diffractive limit, and the whole system designed could satisfy the actual operational requirements.
