硒化铅

当红外光源通过装在步进电机斩波轮上的滤光片照射到硒化铅（PbSe）检测器上时，就会将气体的浓度变成微弱的电信号，经过相关电路处理，最终得到测量结果。

Through filter set up on Stepping-Motor Chopper Wheel , when infrared source irradiate PbSe detecting implement , a faint electronic signal converted from gas consistency is gotten , then processed by relative circuit , finally detection result is exported .
