Abstract
An image intensifier tube and a method of making same are disclosed wherein veiling glare caused by the amplification of off axis light is reduced. Included is a non-reflective, near infrared light absorbing first layer formed on the face plate of the tube adjacent any surface at which off-axis light could otherwise be reflected to the photoemissive device associated with the face plate and an electronically conductive second layer formed on top of the first layer. Such coatings are preferably formed by sputter deposition.
