Two-stage intensifier, with lens and camera (MCP).png

Micro-channel plate (MCP)

The MCP is a thin plate with millions of 6 micron wide channels. An electron coming from photocathode will be accelerated towards the MCP where it is multiplied. The electron gain can be controlled by adjusting the MCP voltage.

For single-photon detection, an image intensifier can be equiped with a dual MCP to provide a higher electron gain.
