FAQ:

• These units will come with tube data sheets and a 10 Year Extended Warranty through TNVC in addition to the L3Harris Factory Warranty

• They will not come with the standard TNV accessories (NVG pouch/cleaning kit)

• These units will come with the L3Harris 4x AA Cold Weather Battery Pack (CWBP) and 25” 90 degree cable connector, as well as the full factory accessory kit – THIS DOES NOT INCLUDE EXTRA DIOPTER INSERTS. The standard diopter is -0.50, this is optimized for the 95^th percentile of users, alternate diopters will be special order items.

• THE L3HARRIS BNVD-SG FEATURES NON-ADJUSTABLE DIOPTERS. THE STANDARD INCLUDED DIOPTER IS -0.5, HOWEVER, DIOPTERS TO MATCH EYE PRESCRIPTION (INCLUDING SPARE PARTS) ARE AVAILABLE FOR PURCHASE HERE . SEE BELOW FOR MORE INFORMATION.

• • The standard diopter lens of -0.5 results in a system diopter of -0.5.  This means the eyepiece is focused to a distance of 2 meters  (1 ÷ 0.5).  This is typically a comfortable point of focus for the eye when either having good uncorrected or corrected vision.  So if an individual is using the BNVD while wearing their corrective eyewear they should use the -0.5 diopter.  However, if that individual is using the BNVD without their prescriptive eyewear then they would take their optical prescription and subtract 0.5 from it to determine the proper screw on diopter.

Introducing SuperGain:

Introduced commercially by TNVC in partnership with L3Harris, SuperGain is the latest image intensifier tube technology and one of the most significant evolutions in Generation 3 night vision systems and performance since the introduction of Unfilmed technology and available at TNVC as a new premium option. 

Over the years, TNVC has been fully committed to making the very best and most advanced, High-Performance MIL-SPEC, duty-ready night vision, thermal, and visual augmentation systems technology available to ALL customers.

Manufactured by L3Harris and distributed by TNVC, SuperGain Unfilmed White Phosphor image intensifier tubes are already in use with the United States military, including Special Operations Forces in some of the DoD’s most elite formations. These new SuperGain image intensifiers increase the Luminance Gain (Gain) specification from the standard 40,000-80,000 fL/fc to between 100,000-120,000 fL/fc, greatly increasing the image intensifier’s ability to amplify and collect light, resulting in a noticeably brighter image with increased low light performance and extending operational envelope and ability to see into dark areas.

***ALL SYSTEMS WILL BE 2376+ MINIMUM FOM***

SuperGain image intensifier tubes have undergone extensive testing both by the U.S. Army’s Night Vision and Electronic Sensors Directorate (NVESD) at Fort Belvoir as well as USSOCOM and other Special Operations Forces organizations, and are currently being fielded and in-service around the world in the newest, most technologically advanced night vision systems in the force, including the AN/PSQ-42 ENVG-B Advanced Goggle as well as panoramic fusion goggles.

From the end-user’s perspective, the SuperGain tubes will be noticeably brighter than standard Unfilmed White Phosphor tubes under most conditions and will provide more useable information in extreme darkness. However, the most significant difference that users in the field will see is the ability to see deeper into dark corners and underbrush, allowing them to detect potential threats beyond the range of typical image intensifiers. This can be a significant advantage in both urban areas / inside of structures as well as in more rural areas with vegetation and heavy canopy and subterranean operations.

While many consumers, both government and commercial have been focused on FOM (Signal to Noise Ratio multiplied by Center Resolution expressed in lp/mm) as a metric for image intensifier performance and image quality, with manufacturers pushing the envelope of performance through improved methods and processes.

Luminance Gain is typically set by the manufacturer, and is the measure of how well an image intensifier can amplify light, and is one of the most critically important factors of image intensifier performance–in fact, the term “Failure,” in MTTF (“Mean Time To Failure”), commonly used to describe tube longevity and durability and expressed in terms of hours, is broadly understood to represent a roughly 50% loss of Luminance Gain.

Nevertheless, Gain has typically been set by the manufacturers at a lower setting (in accordance with MIL-SPECs) due to concerns that too much Gain could lead to increased and undesirable noise in the image, which can be true with lower performance tubes. However, with modern advances in tube manufacturing processes and consistency, L3Harris has been able to increase average tube performance by over 50% in the last six years, with modern tubes having less noise overall, allowing L3Harris to increase the tube Gain, and therefore increasing the amount of useful information provided to the user without the same levels of increased noise.

In order to maximize the benefits of the increased Gain and ensure image quality these new SuperGain systems from TNVC will ONLY be available with a minimum Figure of Merit (FOM) specification of 2376+, the highest minimum performance specification currently available to the wide market, and with actual average tube performance exceeding that of current USSOCOM specifications.

Not only do SuperGain tubes provide improved light amplification and more information to the user, but effects can be felt on the user’s end as well—the overall brighter image allows the pupil to remain smaller, even in low light conditions where image intensifier tubes begin to dim, effectively improving the user’s vision and allowing them to take full advantage of the information provided by the SuperGain tube as well as reduce eye fatigue from long term use. Meanwhile, neither image intensifier life, nor reliability are affected, with SuperGain tubes being every bit as durable and reliable as typical Unfilmed White Phosphor image intensifier tubes.

Adopted by USSOCOM as the AN/PVS-31A, the L3Harris BNVD has been in use by U.S. Special Operations Forces for several years as well as allied forces, however they have not been widely available on the commercial market.

The L3Harris BNVD SuperGain is one of the lightest binocular night vision systems on the market, with unparalleled optical performance with lightweight optical lens assemblies optimized to maximize the performance of the SuperGain Unfilmed 2376+ FOM (figure of merit) White Phosphor image intensifier tubes, and features both an onboard AA battery and an external power connector to be used with an external power supply.

These systems will be available and ship direct from TNVC with the complete 4x AA Cold Weather Battery Pack and 25” BNVS power cable with full factory warranty and customer support. Each SuperGain unit will also come with factory image intensifier Tube Data Records with a 100-120K fL/fc Luminance Gain setting and minimum figure of merit (FOM) of 2376+.

These units are NOT contract overruns—these are brand new manufactured units, and they will be available as regular stocking units from TNVC, though demand is expected to be extremely high.

The L3Harris Binocular Night Vision Device (BNVD) is compact, lightweight, articulating, dual tube Gen3 goggle to replace the legacy AN/PVS-15 in the USSOCOM inventory, and adopted by the U.S. military as the AN/PVS-31.  Weighing in at just under one pound, this system is almost as light as a monocular, yet packs in the same feature set (and then some) of much heavier devices.

Working directly with U.S. Special Operations Forces’ input, the BNVD was designed to increase system resolution, significantly reduce head borne weight, improve system of center of gravity, provide additional operational utility, and improve overall operator situational awareness.

The newest BNVD-SG (SuperGain) also utilizes SuperGain tubes developed in concert with the U.S. Army’s Night Vision and Electronic Sensors Directorate (NVESD) at Fort Belvoir and U.S. Special Operations Forces.  SuperGain is the latest image intensifier tube technology from L3Harris, and is one of the most significant evolutions in Generation 3 night vision systems and performance since the introduction of Unfilmed technology and available only at TNVC as a new premium option.

SuperGain tubes have a Luminance Gain setting of between 100-120K, greatly increasing the image intensifier’s ability to amplify and collect light, resulting in a noticeably brighter image with increased low light performance and extending operational envelope and ability to see into dark areas. In addition, all TNVC SuperGain systems have a 2376+ Minimum Figure of Merit (FOM) specification, the highest performance level available to the wide market.

The BNVD SuperGain is variable gain-capable, allowing operators to adjust the brightness of their image as situations on the ground dictate.  Gain adjustment is quick and easy; done by simply rotating the power button.  This centrally-located control activates and deactivates the goggle when pressed and held in for two seconds, making all controls easy to locate and operate without being able to see them and while wearing gloves.  There is no integral infrared illuminator in the L3Harris BNVD-SG.  This feature was not desired by most operators due to its limited distance functionality and added weight/size.

The BNVD can run off a single on-board AA battery or a remote battery pack mounted behind the helmet for extended use.  The remote pack allows the goggle to weigh in even less and acts as a counterweight to the entire system.  It also features built-in dual infrared strobe lights for ground personnel identification.  The strobes can be easily activated by a small protected switch under the battery housing.  One thing to note is that the cable connecting the goggle to the remote battery pack will slightly interfere with the right tube’s ability to be pivoted up (see below).

The L3Harris BNVD has independently pivoting or articulating optical pods to adjust interpupillary distance (IPD) or to allow the goggles to be stowed flat, rather than articulating the mount to a stowed position, allowing greater overhead clearance and easier access to deploy the goggle when needed. The articulating optical pods can also allow the user to run the goggle in a binocular or monocular configuration.

 

Export of Night Vision Equipment or related accessories (such as manuals) is strictly regulated by the US Department of State in accordance with the guidelines of the International Traffic in Arms Regulations (ITAR). It is a major crime to ship or carry US manufactured night vision devices outside the borders of the United States, punishable by fines and prison sentences. Ignorance of these regulations will not hold up in court. By purchasing night vision equipment from TNVC, you attest that you will not attempt to export or carry this night vision equipment outside the borders of the United States. Also, it illegal to allow a non-US Citizen to look through US Gen3 Night Vision Devices, even on US soil. Again, this is a crime punishable by fines and prison sentences.
