摘　　要：无热化技术是保证工作在非设计温度下光学仪器性能的关键所在。与主动无热化技术和光学被动无热化技术相比,机械被动无热化技术在红外光学系统消热设计中具有一定的优势。在光学、机械仿真的基础上,镜头采用高膨胀系数的塑形材料以及合理的结构设计实现了无热化设计与制造。测试与试验表明,该镜头在-40℃^+60℃工作温度范围内具有良好的成像质量。Athermalization is the principle of stabilizing the optical performance with respect to temperature, Compared with active athermalization and optical passive athermalization. Mechanical passive athermalization has some advantage for infrared optical system. Based on optical and mechanical simulation, the infrared lenses was designed and fabricated with athermalization via reasonable mechanical structure and plastic material with high linear expansion coefficient. Test shows that the lenses has favorable performance between -40 ℃ and ＋ 60 ℃.
