CN203519490U 一种气体光谱吸收型传感装置 有权

一种气体光谱吸收型传感装置
摘要：
本实用新型涉及一种气体光谱吸收型传感装置,其不同之处在于：其包括外壳、DFB激光器、准直透镜、反射镜组、探测器、锁相放大器、激光器驱动和温度控制单元、微处理器、液晶显示单元，所述准直透镜与反射镜组固定在所述外壳上，外壳底部留有气孔，准直透镜与反射镜组之间留有间隙，各个射镜之间均留有间隙。本实用新型体积小，灵敏度高，结构简单。
摘要（英）：

The utility model relates to a gas spectrum absorption-type sensing device. The as spectrum absorption-type sensing device is characterized in that the gas spectrum absorption-type sensing device comprises a shell, a DFB (distributed feed back) laser, a collimating lens, a reflector group, a detector, a lock-phase amplifier, a laser drive, a temperature control unit, a microprocessor and a liquid crystal display unit, wherein the collimating lens and the reflector group are fixed on the shell; the bottom of the shell remains an air hole, a gap is arranged between the collimating lens and the reflector group, and gaps are arranged among reflectors. The gas spectrum absorption-type sensing device provided by the utility model has the advantages that the volume is small, the sensitivity is high, and the structure is simple.
