Abstract: Microchannel plates for use in image intensifiers and night vision devices having both improved gain and signal-to-noise ratio are provided. The microchannel plates provide an initial electron impact area having a surface electron-emissivity coefficient greater than one (1) that is not occluded by low electron-emissivity conductive coatings. In one embodiment angulated deposition of a coating material is used to provide a high electron-emissivity initial electron-impact area while in another embodiment nonmetallic electrodes provide increased amplification of a signal electron. Besides improving gain and sensitivity, the microchannel plates of the present invention provide a higher signal-to-noise ratio, better resolution, high open area ratios and are significantly more cost effective to produce.
