大面积微通道板型光电倍增管是一种将极微弱光信号转换成电信号的真空电子器件，具有探测面积大、探测效率高等优点。本产品使用Sb-K-Cs阴极作为光电转换阴极，该阴极对350-450nm波段光子的转换效率高；应用微通道板作为电子倍增管系统，可以实现10⁷以上的电子增益，微通道板的倍增距离短，因而具有优越的时间分辨率。 产品性能可以按客户需求订做，目前主要产品有8英寸和20英寸微通道板型光电倍增管。

The large-area MCP-PMT is a vacuum electronic device that converts extremely weak light signals into electrical signals. It is a large-area, high-detection efficiency electrostatic focusing pho - tomultiplier tube with independent intellectual property rights. This product uses Sb-K-Cs cathode as a photoelectric conversion cathode, which has high quantum efficiency for photons in the 350-450nm wavelength; using a microchannel plate as an electron multiplier tube system, the superposition of two microchannel plates can achieve an electron gain of more than 10⁷ , The multiplication distance of the microchannel plate is short, so it has superior time resolution. Product performance can be customized according to customer needs. At present, the main products are 8-inch and 20-inch MCP-PMT.
