微通道板是由数百万个微小通道电子倍增器组成的三维电子倍增列阵，是对二维空间分布的电子流进行多次倍增的元件。微通道板是微光像增强器的核心元件，作为一种具有快速时间响应和二维空间分辨能力的通道式电子倍增器，还可以直接探测各种高能粒子及射线等。夜视集团生产d16mm、Φ25mm、Φ33mm和Φ36mm像增强器用标准微通道板以及其他各种特殊用途的微通道板，年产量超过10万片。

The microchannel plate is a three-dimensional electron multiplying array composed of millions of tiny channel electron multipliers, and it is an element that multiplies the electron flow distributed in two-dimensional space for many times. The micro-channel plate is the core component of the low-light image intensifier. As a channel-type electron multiplier with fast time response and two-dimensional spatial resolution, it can also directly detect various high-energy particles and rays. Night Vision Group produces standard microchannel plates for d16mm, Φ25mm, Φ33mm and Φ36mm image intensifiers and other microchannel plates for various special purposes, with an annual output of more than 100,000 pieces.
