The Generation 3 OTN-321B binocular features the latest rugged military design
with specialized multicoated optics. The light weight OTN-321B features 3.2x magnification, Automatic Brightness Control (ABC),
a built in IR illuminator, and bright light protection. Its unique dual tube/dual eye configuration is the only night vision
device that offers a true stereoscopic night vision image. The innovative wide exit pupil design eliminates the need for interpupillary
adjustment and reduces the size and weight of the unit. The optional head-mount assembly and 1x lens kit convert the 321 from
a binocular to a goggle, making the 321B the most versatile dual tube system available.
