Abstract: A clip-on power source for powering an ANVIS binocular. The power source has an electrical interface that enables the power source to be detachably coupled to the ANVIS binocular. The interface also enables the power source to pivot relative to the binocular from a first position to a second position to power-on and power-off the ANVIS binocular.

Abstract: A modular night vision device wherein either one or two night vision monocular assemblies can be joined to a common mount to selectively create either a monocular night vision apparatus or a binocular night vision apparatus. Electrical contacts are present on the night vision monocular assemblies that couple to the common mount. The electronic controls and power source needed to operate the night vision monocular assemblies are contained within the common mount. Accordingly, the night vision monocular assemblies automatically become disabled when detached from the common mount. The common mount provides interpupillary and distance-to-eye adjustments for the night vision monocular assemblies. Additionally, the common mount enables the night vision monocular assemblies to be flipped up to a stowed position out of the field of view of the person utilizing the night vision device.
