About this deal

The L3Harris BNVD 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 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. The DTNVGs do have a slight advantage over the 1431. When you roll up a monocular pod, it will shut power to the intensifier tube. Not the case with the 1431. One feature that the 1431 shares with the DTNVG is the auto off/on when the unit is stored vertically on a helmet. However, just like the PVS-31, the 1431 can be programmed. The DTNVG can supposedly be programmed as well but it is not something the user can perform. On the 1431 you press the power button 4 times and a red indicator light will blink inside the left eyepiece. You are now in auto off mode. If you press the power button 4 times again then the unit will no longer shut off when stored vertically. You must do this when the 1431 is turned on. Its lightweight design ensures comfort during prolonged use, and the option for hands-free operation with various mounting choices adds to its appeal. The RNVG provides crystal-clear night vision, ensuring clear observations in low-light conditions. PVS31 Night Vision

The AN/PVS-31A uses L3Harris Unfilmed White Phosphor autogated image intensifier tubes with a 2376 min FOM rating from the factory. These unfilmed tubes provide incredible clarity, low light and high light performance, and increased depth perception. These are L3’s most advanced intensifier tubes and offers significant performance increases over other white phosphor systems. PVS 31 has a better build and design than PVS 15. Both PVS 15 and PVS 31 are generation 3 military-grade night vision binoculars. So the build of these two binoculars has a lot of similarities. One of the most sought after and frequently requested night vision products now on the commercial market-the L3Harris Binocular Night Vision Device (BNVD)! Items sold as part of a special offer or a bundle with a free product (excluding our free keychain torch offer) are not included in the price match offer. This article will provide a detailed comparison between the two products, focusing on their features, price points, and associated accessories. The performance and image quality, ergonomics, durability, and battery life of each model will also be discussed.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. Despite this, the DTNVG also shares the RNVG’s lightweight design and rugged build, making it suitable for outdoor activities and tactical operations. The BNVD’s twin-tube design offers greater reliability in the field against failure or damage versus a single-tube night vision devices. Manual system gain adjustment allows operator to control image brightness to match the environment. The BNVD also can be used as a monocular by rotating either left or right channel, up and out of the way. In The Box

When it comes to performance and image quality, the AN/PVS-31A and SI/PVS-14 NVGs offer distinct capabilities that can help inform a buyer’s decision. What sets the RNVG and PVS-31 apart in night vision devices? Delve into their features, benefits, and optical capabilities as you embark on this comprehensive comparison. The PVS 15 has room for only one 1.5 volts AA battery. The binocular would last 15-16 hours with a fully charged battery. The PVS 14 fails to turn on due to battery issues sometimes.

SPECS

AN/PVS-31D (F5032) White Phosphor Dual Tube Goggle 2400+ FOM Minimum. All AN/PVS-31D (F5032) Ship With A G24 Lite Helmet Mount. 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. Articulating NODs (Night Observation Devices) are more desirable than standard binocular night vision goggles. They are flexible in that the eye pods aka monocular pods are articulated and roll upwards like gullwing doors on a Delorean. The PVS 15 is bigger and heavier than PVS 31. When it comes to binoculars, the lightweight and compact the size is, the better it is for the user. The dimensions of the PVS 31 are 4.3” L x 4.3” H x 3.4” W. This is one of the reasons PVS 15 and PVS 31 are good to use in the combative field. Because more of the surroundings are visible with them. Resolution:

With each battery capable of holding out 16 hours, the binoculars’ total battery life is about 50 hours. So, you can take your PVS 31 for a long tour without worrying about running out of battery power. So, PVS 31 wins. Price Range: Comparing two advanced generations of night vision goggles, the AN/PVS-31A and the SI/PVS-14, reveals different levels of performance and features. 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. 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.

As mentioned earlier, the RNVG boasts a wider field of view, making it suitable for scenarios where broader visual coverage is crucial. The AN/PVS-31A is a Gen III dual tube goggle with improved white phosphor tube technology. It offers superior situational awareness compared to a single tube goggle, with a low-profile design and improved system resolution. It also provides additional operational utility and reduces head-borne weight, allowing for improved system center of gravity.

Although they have a good tolerance level it’s not rigid enough. Due to the fact that most of the housings are plastic. However, PVS 31 is more rigid than PVS 15. The SI/PVS-14 Elbit Thin Filmed White Phosphor is a Gen 2 Commercial offering that provides a thin filmed white phosphor. It also provides an optional Steele Protective Lens, which offers additional operational utility. One of the most sought after and frequently requested night vision products now on the commercial market—the L3Harris Binocular Night Vision Device (BNVD)! 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. Pinnacle Elite Image Intensifier Tubes offer the ultimate in picture clarity due to stringent cosmetic standards that allow only a few IITs to qualify for the Pinnacle Elite designation. Pinnacle Elite tubes have almost 90% less imperfections than our Bravo tubes, only allowing up to two blemishes – one in Zone 2 and one in Zone 3, but microscopically small at under six mils. Every Pinnacle Elite tube has a minimum of 2000 FOM, combining top-end performance with a nearly pristine image. Armasight systems with Pinnacle Elite Image Intensifier Tubes are the systems of choice for law enforcement, military, and the most accomplished hunters.

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. Yes, they can be used in day time as well. During the day, the original image will be shown without using infrared. However, the visibility won’t be very clear under bright sunlight. After all, they are designed for low-light vision. What’s the difference between binoculars and night goggles? The DTNVG (Dual Tube Night Vision Goggle) combines the benefits of both RNVG and PVS-31. A design similar to the PVS-31 provides the advantage of dual tube technology, offering excellent depth perception.
