An intensified charge-coupled image sensor comprises an image intensifier section and a header assembly. The header assembly includes a charge coupled device and an insulative header for retaining the charge-coupled device. An imaging aperture having a sidewall is formed in the insulative header. The imaging aperture is disposed about an optical axis of the image sensor. A conductive layer for preventing electrostatic charge buildup resulting from the impingement of photoelectrons emitted from a photoemissive cathode is provided on a first major surface of the header and on the sidewall bordering the imaging aperture. The header includes an electrode surface having a plurality of discrete contact pads thereon. A header input member has a substantially rectangular portion attached to a first major surface of the insulative header and an annular portion attached to the image intensifier section of the image sensor. A header output member has a substantially rectangular portion attached to a second major surface of the insulative header. The other end of the header output member is closed off by the end-closure cap.

An electrostatic shutter tube comprises a photocathode adapted to emit electrons along a path as an electron image in response to a radiant image incident upon the photocathode. A phosphor screen is spaced from the photocathode and is adapted to emit a light image in response to the impingement of the electron image thereon. A shuttering grid is disposed in the electron path between the photocathode and the phosphor screen to control the emission of the electron image. An anode member adjacent to the screen has therein a pair of primary deflection plates disposed along the electron path for deflecting the electron image in a first direction across the screen. A pair of secondary deflection plates are disposed within the anode member, along the electron path, in a cross-over region of the electron image. The pair of secondary deflection plates are substantially orthogonal to the pair of primary deflection plates and provide deflection of the electron image in a second direction across the screen, which is different from the first direction.

An image intensifier tube includes a substantially cylindrical envelope having a photoemissive cathode at one end and a phosphor screen at the other end. A tubulation extends through the envelope wall for introducing a constituent of the cathode into the envelope. A baffle ring comprising an insulative material is located within the tube adjacent to the tubulation. The baffle ring forms an interior annular chamber with the cylindrical envelope. An annular passage is formed between the baffle ring and an inwardly-extending portion of the envelope.
