Abstract
A vacuum-tight envelope (601) having a terminal element (610) bearing the envelope's output window. An output screen (605) is glued to the inner face of the output window by a first glue (608) having the same refractive index as the output window. The envelope's terminal element is made unitary with a (611) of the envelope by vacuum-tight mounting (609). An optional anti-reflection coating (674) may be deposited directly onto the external face of the output window.
