A night vision device (30) with an image intensifier tube (34) including an improved microchannel plate (42) which has a thickness no more than about 110 % of the value indicated as optimum by the theoretical Universal Gain Curve. Accordingly, the microchannel plate (42) provides an improved resolution, and reduced operating voltage, and still provides a level of electron gain favorably comparable to conventional microchannel plates.
