The Iris 221 (Generation 2+) or Iris 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 Iris Binocular converts easily into the 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 head gear assembly for hands-free use.

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