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. 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. 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.

Now, let’s compare these two exceptional night vision devices across various parameters to better understand their strengths and weaknesses. 1. Optical Performance 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.

Determining which night vision goggles are the most suitable for individual needs can be a difficult decision depending upon ergonomics, durability, and battery life. The AN/PVS-31A BNVD and the SI/PVS-14 Photonis Echo White Phosphor are two of the most popular night vision goggles on the market. Both offer superior situational awareness and several options for customization, as well as a variety of features to consider when assessing their ergonomics, durability, and battery life. The Armasight PVS-31 with Gen 3 Pinnacle Elite White Phosphor Image Intensifier Tubes are manufactured exclusively for Armasight by Elbit Systems of America. These Night Vision Goggles are a version of their popular F5032 system, which is part of the U.S. Marine Corps’ Squad Binocular Night Vision Goggles (SBNVG). These PVS-31 night vision goggles stand out among competing options because they have variable diopters, a built-in IR illuminator, and Elbit’s thin-filmed image intensifier tubes (IIT). The IIT are known for retaining peak performance over countless usage hours, combining extremely high performance with nearly impeccable cosmetics. In fact, the allowable blemishes are 50% lower than Pinnacle IITs, providing a flawless Zone 1 picture. They have a minimum of 2,000 FOM with a higher signal-to-noise ratio (SNR) and no inclusions in Zone 1. Plus, these tubes only allow 1 inclusion in Zones 2 and 3, and it can’t be bigger than 0.006 inches, so it’s virtually imperceptible.

Dual Tube Configuration: The PVS-31 utilizes a dual tube system, providing a stereoscopic vision that enhances depth perception and situational awareness. These units will come with tube data sheets and a 5 Year Extended Warranty through TNVC in addition to the L3Harris Factory Warranty You can count on at least 10,000 hours of operation out of the Armasight PVS-31 NVGs, and they are battle-tested by some of the most experienced special operation fighting forces in the world. All PVS-31s come with a Wilcox Industries G24 Breakaway Mount, so you can immediately attach them to a compatible shroud on your tactical helmet.

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. Regarding weight, the RNVG is lighter than the PVS-31, which can be advantageous during extended missions or activities requiring minimal additional weight on the head. RNVG Vs PVS31 Vs DTNVG Night Vision Longer Battery Life: The PVS-31 has power-efficient components, resulting in extended battery life for prolonged operations. DEALER PRICING AVAILABLE ONLY TO PROFESSIONAL LEVEL DEALERS – DIRECT ALL DEALER INQUIRIES TO OUR DEALER SALES PROGRAM. 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.

L3 AN/PVS-31A BNVD Night Vision Binocular with High performance Gen 3 Unfilled White Phosphor image intensifiers 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: In conclusion, the RNVG and PVS-31 are exceptional night vision devices, each with unique features and advantages. The RNVG’s wider field of view and lightweight design make it an excellent choice for outdoor enthusiasts and individuals seeking enhanced mobility. In conclusion, both the PVS-31 and PVS-15 are top-of-the-line night vision systems that offer impressive capabilities for tactical operations and other low-light scenarios. While there are some key differences between the two models in terms of design, features, and performance, both offer a high level of functionality and dependability. Finally, the AN/PVS-31A BNVD has a single battery life of 15 hours, while the SI/PVS-14 NVG has a single battery life of 10 hours. When using four batteries, the AN/PVS-31A BNVD has a battery life of 50 hours, while the SI/PVS-14 NVG has a battery life of 40 hours. This makes the AN/PVS-31A BNVD the better choice when it comes to battery life. Feature

Thanks to dual-tube design, PVS-31C-MOD delivers depth perception and allows using PVS-31C-MOD to operate various machines, boats etc., in addition to basic ground operations. A dual-tube night vision system has proved to be safer and more effective in low-light conditions compared to a “bi-ocular” system, commonly known as “PVS-7”, which is a “one lens-two eyes” type of NVD. Before jumping on to the long discussions, let’s take a look at the fundamental differences between both binoculars. Aspects 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.

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. Overall, it’s clear that the PVS-31 and PVS-15 are two of the best night vision systems available on the market today. With their advanced features, rugged construction, and reliable performance, they are the perfect choice for anyone who requires the very best in nighttime vision technology.
