Export Restrictions

All Gen 3 and Gen 2+ night vision image intensifier tubes and devices as well as thermal sensors and devices are subject to United States export rules and regulations. Valid export licenses may be issued by the U.S. Department of State, Directorate of Defense Trade Controls, in accordance with the International Traffic in Arms Regulation (ITAR), Title 22, Code of Federal Regulation 120-130; or by the U.S. Department of Commerce in accordance with the Export Administration Regulations (EAR), 15 CFR Parts 730-774.


The D-221 (Generation 2+) or D-321 (Generation 3) high performance, modular, hand-held night vision binocular uses dual image intensifier tubes to provide crisp, clear images in the darkest conditions.

The binocular includes advanced features of automatic brightness and gain control. Each image tube operates independently, providing excellent redundancy. The unique patented design eliminates any need for interpupillary adjustment and reduces the size and weight of the unit. An integrated near IR illuminator enhances the ability to operate the goggle in confined spaces.

The powerful 3.6x D-221B/321B Binocular converts easily into the D-221G/321G 1x night vision Goggle with a 40 wide field of view by simple replacement of front objective lenses. The goggle attaches quickly to an ambidextrous headgear assembly for hands-free use.

The D-221/321 is the most affordable stereoscopic night vision goggle/binocular currently available on the market.
