Abstract
A microchannel plate assembly includes a plurality of microchannel plates that are aligned along a common axis and coupled together. The microchannel plates each have an object-side surface and an image-side surface and the assembly has respective interfaces between the image-side surface and the object-side surface of adjacent microchannel plates. At least one ion barrier film is disposed on at least one of the microchannel plates, but only on the object-side surfaces in the interfaces.
