The night sight includes a focusing assembly having decreased sensitivity to tilt or decenter, and a collimator mounted within a spherical bearing so that the collimator may be precisely aligned during assembly of the night sight. The night sight thereby ensures that an image viewed through the night sight appears to originate from the same angle as that with which the image entered the objective lens, and further resists a need to compensate for parallax during aiming.

An advanced image intensifier assembly provides enhanced functionality. A grounded photocathode provides shielding from electromagnetic interference, improving the ability to work in multiple light conditions. Bi-directional wireless communication and non-volatile storage allow critical information to be permanently stored and read wirelessly at a scanning station, easing in identification of units. Because bi-directional communication components can be embedded within an image intensifier assembly, existing end-user night vision devices can be upgraded by simply replacing the image intensifier assembly. For enhanced safety, a programmable shutdown capability is provided. This renders the device inoperative in the absence of continuous input, either wireless or manual, from an authorized operator, thus rendering the device useless if captured by enemy combatants. Finally, direct 1-volt operation enables the device to be powered by, for example, a single AA battery.
