An image intensifier with an electrophoretic getter device incorporated therein is described. The electrophoretic deposition, in the form of a porous coating, of at least one getter material and simultaneously an antisintering agent on any form of getter support is also described. The getter material may be a powder of a metal, of a metal alloy or of a hydride thereof, or a mixture of these components.
