The multi-use ATN NVMN14-4 is a high-performance modular, hand-held passive Night Vision Monocular. It utilizes a single Filmless and Autogated Gen. 4 Intensifier Tube to provide crisp and clear images under the darkest conditions. The ATN NVMN14-4 "single tube/single eyepiece" approach to Night Vision Scope is based upon the proven concept that independent use of each eye maximizes the ability of the user to operate under a wide range of low-light conditions. This tactic tends to enhance the field of view while reducing the risks of temporary night blindness typically associated with Night Vision Goggles. With the ATN NVMN14-4 the user retains his full peripheral vision in the unaided eye in conjunction with the 40 degree FOV offered by the Night Vision Device. The ATN NVMN14-4 can be hand-held or installed on a variety of standard and optional head-mount/helmet-mount assemblies for handsfree use. The highly modular design also allows the ATN NVMN14-4 to be installed on Reflex Cameras and Camcorders using an optional adapter. The integrated near-IR Illuminator enhances the ability of the user to read maps and operate in confined spaces. The ATN NVMN14-4 can be hand-held or installed in a standard PVS-7 head mount, or it can be installed in an optional dual-carriage head mount, providing a dual-eye configuration. The ATN NVMN14-4 is smaller and lighter then the Mil-Spec PVS-14, and is fully submersible to a depth of 66 feet (20 Meters). The ATN NVMN14-4 works with either a single AA, or 3.5 volt lithium battery offering more flexibility and longer battery life. The integrated IR Illuminator enhances the ability of the user to read maps, and operate in confined spaces. The ATN NVMN14-4 is compatible with most all weapon-mounted IR Laser aiming and illuminating Devices.
