In allusion to electromagnetic radiation damage that existed in daily life, social safety and military field, electromagnetic shielding technology of infrared and infrared optical window was studied. Transparent conductive film mesh was proposed in optical window, the mesh is composed of oxide films including ITO, SnO<sub>2</sub> etc, for decreasing  infrared and <a href="http://dict.cnki.net/dict_result.aspx?searchword=%e5%8f%af%e8%a7%81%e5%85%89&amp;tjType=sentence&amp;style=&amp;t=visible">visible</a> <a href="http://dict.cnki.net/dict_result.aspx?searchword=%e4%bd%8e&amp;tjType=sentence&amp;style=&amp;t=low">low</a> <a href="http://dict.cnki.net/dict_result.aspx?searchword=%e9%80%8f%e8%bf%87%e7%8e%87&amp;tjType=sentence&amp;style=&amp;t=transmission">transmission</a> problem of traditional <a href="http://dict.cnki.net/dict_result.aspx?searchword=%e9%87%91%e5%b1%9e%e7%bd%91%e6%a0%85&amp;tjType=sentence&amp;style=&amp;t=metal+mesh">metal mesh</a>.
