To form microchannels by means of bending processing by subjecting an acid etchable glass to a bending processing, without reducing the diameter size of the microchannels.
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 outer circumferential walls of the acid resistant glass that surround the acid etchable glass. Respective outer circumferential walls form curved surfaces extending longitudinally between the opposing end surfaces. The curved surface is configured to reduce light passing from one end surface to the other end surface. The acid resistant glass has a lower softening temperature than the acid etchable glass.
