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 goggle uses dual image intensifier tubes to provide crisp, clear images in the darkest conditions.

The goggle 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 D-221G/321G Goggle with 1x objectives and 40 field of view attaches quickly to an ambidextrous headgear assembly for hands-free use. With replaced front objectives, the goggle converts easily into the powerful D-221B/321B 3.6x night vision Binocular.

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