| 中文摘要: |
| 针对当前军工红外成像仪器小型化及宽温度适应性的需要,采用光学被动式无热化方法对8~12 μm波段设计了一款镜头。该镜头F数为1、焦距为40 mm、视场为16.8°、温度适应范围为-40~65 ℃。设计结果显示,在要求的温度范围内,系统无需调焦,像质接近衍射极限,达到无热化的性能要求。 |

| To meet the needs of the current military infrared imaging instrument, we designed a lens for 8~12 μm wave band with uncooled optical passive method. The specific parameter,F is 1, focus is 40 mm, field of view is 16.8°. The design results are achieved within the scope of the -40~65 ℃, as close to the diffraction limitation. The system does not need focus. The athermalization performance is good. |
