摘　　要：长波红外探测器是机载红外搜索跟踪系统(IRST)的核心传感器,其成像质量的优劣直接决定了IRST的目标检出等关键技术指标,最终影响IRST的红外探测距离。设计了一套长波标准成像镜头,焦距150 mm,系统总长210mm,调制传递函数达到衍射极限,畸变小于2%,在红外探测器筛选或验收过程中能够准确定量地评价其成像质量。The long-wave infrared detector is the key sensor of the airborne Infrared Search and Tracking（ IRST） system,and its imaging performance directly determines the key parameters of IRST,including the target detection,and finally affects the infrared detecting distance of IRST.A long-wave standard imaging lens is designed to evaluate the imaging performance of the long-wave infrared detector with a focal length of150 mm and a total length of 210 mm.The distortion rate of it is less than 2%,and the Modulation Transfer Function（ MTF） is up to the diffraction limits.The imaging lens can accurately and quantitatively evaluate the imaging quality of the infrared detector during the screening and checking process.
