摘　　要：光电仪器的镜头都需要镜头盖的保护以维持仪器性能、延长使用寿命.文章从光电仪器研制工程实践出发,分类详细总结了常用的光电仪器镜头盖的结构形式和工作原理,阐述了这些镜头盖结构的优点与不足,以及最佳适用场景.在此基础上,提出了一种可应用于光电仪器的新型镜头盖形式——可变光阑式电动镜头盖,这种镜头盖结构原理简单、组件质量小,且不再安装在镜头最前端,故有利于光电镜头在指向机构系统中的静平衡与动平衡装调.The lenses of optoelectronic instruments need the protection of the lens cap to maintain the performance of the instrument and extend its service life.Based on the engineering development of optoelectronic instruments,the structure and working principles of lens caps for commonly used optoelectronic instruments are introduced in detail,and the advantages and disadvantages of these lens caps’structure are summarized,and further,their best applicable scenarios are pointed out.On this basis,a new types of lens caps for optoelectronic instruments are proposed:a diaphragm automatic lens cap.The structure principle of this lens cap is simple,the quality of the components is small,and because it is no longer installed at the front end of the lens,it is conducive to the static and dynamic balance assembling of the photoelectric lens in the pointing mechanism system.
