摘　　要：介绍双光栅透镜系统的消色差原理和设计方法。计算结果表明,这种消色差双光栅透镜系统的允许波长变化范围比单光栅透镜可扩大几十倍,因此,它可有效应用于光波波长随环境改变或具有宽波段的系统中。The achromatic principle and its design method of two-grating lens system are presented.The calculating results show that the permissible Wavelength varying range of the achromatic two-grating lens system can be enlarged by a factor of several decades than that of signle-grating lens. Thus it can be effectively applied to the system that light wavelength varies with outside environment or the system with wide waveband.
