Abstract
A microchannel plate (MCP) is formed from a boule. The MCP includes a plate having opposing end surfaces formed of acid resistant glass and acid etchable glass, and multiple channels extending longitudinally between the opposing end surfaces. The multiple channels are formed by circumferential walls of the acid resistant glass that surround the acid etchable glass. A respective circumferential wall forms a curved surface extending longitudinally between the opposing end surfaces. The curved surface is configured to reduce light from passing from one end surface to the other end surface. The acid resistant glass has a lower softening temperature than the acid etchable glass. As a result, the acid etchable glass may be subjected to a bending process, without reducing the diameter size of the microchannels that are formed after the bending process.
