Description:

The Argus BNVD-31 is a cost-effective articulating night vision binocular system designed to deliver strong performance, practical versatility, and user-friendly operation. It features articulating pods with adjustable joint tension and interpupillary stops, along with a central control knob that functions as both the power switch and variable gain control. The system can be powered by either a single AA battery or an external battery pack for extended operational flexibility.

The housing incorporates proprietary compact objective lenses engineered to maximize light transmission while reducing edge distortion, helping to improve depth perception, image contrast, and flare control whilst reducing overall weight.

These fully assembled units boast Generation 2+ or Generation 3 (GaAs Photocathode, Thin-Filmed) North Night Vision Technology (NNVT) Intensifier Tubes with impressive tube performance, our tube options range from 1400+ to 2000-2200+ Figure Of Merit (FOM). Additionally, all devices undergo Dry Nitrogen Purging and Optical Collimation.

Dioptre Adjustment Information:

THE ARGUS BNVD-31 FEATURES ADJUSTABLE DIOPTERS, HOWEVER, ADJUSTMENT BY THE USER IS NOT RECOMMENDED AND MAY VOID WARRANTY. THE STANDARD DIOPTER ADJUSTMENT IS -0.5. 

SEE BELOW FOR MORE INFORMATION TO DETERMINE ALTERNATE DIOPTERS BASED ON EYE PRESCRIPTION.

The Argus BNVD-31's standard -0.5 diopter configuration establishes a system focal point at 2 meters, delivering ergonomic viewing comfort for individuals with standard or corrected vision. Users wearing prescription lenses should maintain the -0.5 diopter setting for optimal performance. Those operating without corrective eyewear should calculate their required diopter by subtracting 0.5 from their optical prescription value, ensuring precise focus alignment and sustained visual acuity during extended night usage.
