At only 475 Grams the BNVD-SG UL ultra light dual tube goggle with Single Gain Control incorporates new high performance optics that are not only much lighter but also offer higher performance than standard optics. Currently the AN/PVS-14 and most other night vision systems use optics which were only designed for green (P43) phosphor image tubes. However these new BNVD optics were designed specifically to be optimized for both White (P45) and Green (P43) image tubes. The BNVD-SG UL includes features not found in other dual tube goggle designs in this weight class. These features include: EMI compatibility Full Diopter Adjustment Range (-6 to +2) Infrared LED and most importantly: a close focus range of 9.8 inches. This is critical when trying to read maps or do close up work such as clearing a weapons jam. NVD-BNVD-SG UL now features a “Tactical Monocular Cutoff”which turns off power to each channel of the binocular whenever a channel is rotated up out of the users’ line of sight. This eliminates stray light emitting from the monocular eyepiece which would reveal the user to anyone else on the battlefield. The BNVD-SG UL has an automatic system power cutoff whenever the BNVD-SG UL is flipped up into the helmet mounted stow position and then powers back on when it is flipped back down. This feature can also be turned off via a four position ON/OFF switch. The BNVD-SG UL is submersible to 66 feet (20 meters) for up to 3 hours. The BNVD-SG UL is available with an optional battery pack which holds 3 “AA” Alkaline batteries for run times exceeding 50 hours.The BNVD-SG UL can be used with optional 3X Afocal Magnifiers. Each 3X Magnifier can be either slide onto each objective lens or screw into the threads on the objective lenses. For extended use it is recommended to screw them on to prevent the lenses from falling off. These magnifiers transform the BNVD-SG UL into a fixed 3X Magnification Binocular. With our expansive capabilities and strategic partnerships we are able to custom build any of our NVD manufactured products with Image Intensifiers from either Elbit Systems of America® Photonis® or L3Harris®. This includes green and white phosphor and thin or un-filmed image tubes. Like all other NVD products the BNVD-SG UL also features our best in the business 10 year warranty.
