An intensified charge-coupled image sensor has a longitudinally extending optical axis. The image sensor comprises an image intensifier section and a header assembly. The image intensifier section includes an envelope having a photoemissive cathode therein for emitting photoelectrons in a pattern corresponding to the intensity of radiation incident thereon. The header assembly includes a charge-coupled device for receiving the photoelectrons from the cathode, an insulative header and a header flange attached between the insulative header and the image intensifier section. The header assembly is improved by the inclusion of an annular support flange which is coaxially disposed within the header flange. The support flange has a projection that abuts the insulative header. A charge-coupled device support assembly is eccentrically disposed within and attached to the annular support flange. The support assembly includes a lower support member and an upper tensioning member for tensioning the charge-coupled device and for exposing at least a portion of the device to the photoelectrons from the cathode through an aperture formed in the upper tensioning member. The exposed portion of the charge-coupled device is centered about the optical axis of the image sensor.
