摘　　要：瞄准镜、高温炉内窥镜、复印镜头、大倍率变焦系统等光学系统中,通常采用中继系统实现系统的延长、转向和系统出入瞳的匹配等等。本文探索了一种实现超宽带宽中继光学系统的像差矫正要求、玻璃选择方法以及设计结果,完成了超宽波段中继光学系统的设计,Zemax的设计结果表明,在工作波段0.4~1.7μm,物方NA=0.2,视场为10 mm的要求内,系统的MTF接近于衍射极限,轴向色差小于40μm,成像质量较好。In optical sights,high temperature endoscope,copy Lens and large range zoom lens and other optics systems,often employ relay systems to achieve system extension,image erection and pupil coupling.In this paper,a design of super-wide band relay system is proposed to realize the aberration correction requirements,glass selection method and obtain the design results.The results of Zemax showed that with working spectral range 0.4~1.7μm,NA=0.2 and 10mm field of view,the MTF of the system is almost diffraction limited,with an axial color difference of less than 40μm and the imaging quality is good.
