GDB-54B型光电倍增管是我厂最近研制的新产品,属多碱阴极光电倍增管系列,它是将GDB-54型管子的平板窗改为棱镜窗而成,是GDB-54型的派生管。它的特点是利用窗的棱镜结构,使光线在阴极层内发生全反射,提高光的利用率。因而它比普通平板窗S-20阴极管子有更宽的光谱响应范围和更高的量子效率,尤其是红光量子效率。用于探测可见光和近红外光信号时,可以获得较高的信噪比。这种管子适用于光度计量、光谱分析、化学发光测量、激光探测、彩色电影的电视播放、电子分色、天文学等领域。 GDB-54B photomultiplier tube is a newly developed product of our factory. It belongs to the multi-alkali cathode photomultiplier tube series. It is made by changing the window plate of GDB-54 tube into prism window and is a derivative of GDB-54 tube. It is characterized by the use of the prism structure of the window, the total reflection of light in the cathode layer, improve light utilization. As a result, it has a wider spectral response range and higher quantum efficiency than conventional S-20 cathode tubes, especially the red quantum efficiency. Used to detect visible and near-infrared light signals, you can get a higher signal-to-noise ratio. This tube is suitable for photometric, spectral analysis, chemiluminescence measurement, laser detection, color film television broadcast, electronic color separation, astronomy and other fields.
