Abstract
The invention includes a microchannel plate for an image intensifier tube, in which the plate has multiple microchannels extending in a longitudinal dimension between transverse surfaces of the plate. Each microchannel includes a first portion forming a first opening at an end proximate a surface of the plate. The first portion includes a wall extending longitudinally from the surface and terminating in a substantially similar first opening at a distal end. The microchannel also includes a second portion of the wall, extending longitudinally from the first opening at the distal end and tapering toward a second opening at a further distal end. The first opening at the proximate end has a diameter that is substantially similar to a diameter of the first opening at the distal end. The first opening is also wider than the second opening.
