Overview

PVS31 is a high performance binocular night vision device. It is featured by high resolution optics, compact housing and ultra light weight. It can be installed with Gen2+ multi-alkali cathode or Gen3 gallium arsenide cathode intensifier tubes. The system image resolution can be as high as 72 lp/mm, and FOM as high as 3000, depending on tubes installed. Unlike similar legacy systems, the PVS31 lenses are designed with quick disassembly features. This innovation allows users to field-stripe the lenses and tubes for maintenance and trouble shooting. With optimized structure and patented material, the system weight is below 450g (w/ tubes and w/o battery). With the high image quality, ultra low weight and robust structure, the PVS31 allow its users to train and operate under complex scenarios and harsh conditions. It is especially helpful in improving situation awareness and combat effectiveness of special force units.

How to Operate

1)Flip Up Power Off When the device is installed on a helmet or head mount, it will automatically turn off after it is completely flipped up over head. When the device is flipped down, it will automatically turn on. It will only turn off when it the flipping angle is greater than the predefined threshold, therefore, raising head will not turn off the device.

2)Dormancy The gravity sensor checks its posture all the time. If the device stay still for more than 100 seconds , it will automatically go dormant to save power and protect the tube from long-time burning damage until the device is waken up by new movements.

3)Manual Gain Control After correctly installing different 37mm manual gain tubes (i.e. Photonis and NNVT three-pin tubes, US MX-11769 tubes and tubes with flying wires) according to our tube installation manual, the user can rotate the power switch clockwise and anti-clockwise to manually control the intensifier’s gain features.
