The Generation 2+ OTN-221B binocular features the latest rugged military design
with specialized multicoated optics. The light weight OTN-221B 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 221B
from a binocular to a goggle, making the 221B the most versatile dual tube system available.
