The image intensifier as we know it today is a direct result of the military need for night vision. The intensifier was developed and produced for that purpose as its primary application. Production of the intensifier therefore is based upon a Military Specification (Mil-Spec) and insures the intensifiers has scientific applications based on its low light sensitivity, spectral response, and gating characteristics. The non-military applications for the image intensifier do not create a large market and therefore these users must adapt the Mil-Spec manufactured device to their specific needs. The intensifier is especially adaptable to the intensified video application when mated to a CCD, CID or CMOS camera. Adapting the intensifier to the video camera creates an indispensable tool for scientific researchers and creates challenges for the camera builder. The military production requirements present many technical specification conflicts for the intensified camera manufacturer and his customers. Properly specifying, selecting and incorporating the image intensifier in the video camera can enhance video camera applications of the image intensifier.
