摘　　要：根据常用大气窗口和常见物体辐射峰值波长，计算出黑体在233-313K范围内的光谱辐射出射度，结合红外探测器的光谱响应曲线得到非制冷红外镜头的设计波长及其权重。将该方法应用于实际物镜设计，发现光学系统波长及权重符合探测器焦平面输出信号光谱响应特性。该方法对非制冷红外热像光学系统的设计具有实际意义。Based on normal atmosphere window and radiation wavelength peak of natural objects, black-body radiance in 233-313K is computed in the paper, and then wavelength and weight for un-cooling infrared object lens are gained from radiation curve of the detector. Applying this method to the lens design, the lens＇ wavelength and weight corresponds to spectral response features of the output signal in the detector＇s focal plane. This method has a practicable significance to the un-cooling infrared object lens design.
