求翻译：The design method and result are described for an infrared afocal zoom system. Its zoom ratio is 4, and the corresponding field of view is 3°~12°. The working waveband is from 7.5µm to 10.5µm, and its total length is required to be no more than 350mm. The final optical system consists of 7 elements, with aspheric surfa是什么意思？ 待解决

无焦红外变焦系统的设计方法和结果的描述。其变焦比为4，和相应的字段是3°〜12°。工作波段是从7.5μm到10.5μm，其总长度不小于350mm。最后的光学系统包括7个元素，非球面和衍射光学元件。它实现了在远红外波段的衍射极限的成像。从设计，可以得出两个结论。 （1）采用衍射光学元件，红外光学系统的设计是一个有效的方法来控制色像差，从而无需使用具有异国情调和昂贵的材料，并有助于降低系统成本;（2）如功能轴向移动系统中的单一元素，可以通过改变视场，对象集中在有限的距离和athermalizing系统。
