Abstract
A system and method associated with a charge drain coating are disclosed. The charge drain coating may be applied to surfaces of an electron-optical device to drain electrons that come into contact with the charge drain coating so that the performance of the electron-optical device will not be hindered by electron charge build-up. The charge drain coating may include a doping material that coalesces into clusters that are embedded within a high dielectric insulating material. The charge drain coating may be deposited onto the inner surfaces of lenslets of the electron-optical device.
