ABSTRACT:
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.
