This invention relates to a camera head enclosure apparatus configured to allow the interchangeability of photo-electric pixel arrays for use in various applications. A personality plate specifically configured to receive and secure a photo-electric pixel array of a particular configuration provided on a chip is disclosed. The invention allows a user to interchange photo-electric pixel arrays, and their respective personality plates, while using the same camera head enclosure, thus enabling the camera head enclosure to be adapted to an entirely different photo-electric pixel array and eliminating the need to custom make camera head enclosures for each application. One embodiment of the camera head enclosure apparatus disclosed further includes a plurality of carriers configured to hold a respective plurality of circuit boards associated with the particular photo-electric pixel array selected. In addition, in one embodiment of the disclosed invention, the camera head enclosure apparatus includes an aperture adjustment assembly which permits alignment of the camera aperture with the photo-electric pixel array to provide the capability to accommodate different types, sizes, and configurations of photo-electric pixel arrays.
