摘　　要：本文设计了焦距50mm,波段为8～12 μm,F数达0.8,全视场10°的适用于非制冷焦平面阵列探测器的红外物镜.分别设计了四片全折射式和三片折衍混合式两种镜头.从两个镜头来看,折衍混合式不仅在体积上小于全折射系统,同时在成像质量和色差上（从10.1μm降至0.8μm）也优于全折射系统.Infrared lenses are designed with focus 50mm, wave.band 8 - 12μm, F-number 0.8 and field of view 10° to meet the need of uncooled focal plane array（UFPA） sensor. A four-piece all refrative and a three-piece hybrid refractive-diffractive infrared lenses are designed. From the result the latter is lighter than the former and its image quality simultaneity excel the former.
