• What is the minimum Figure of Merit (FOM) for the L3Harris GPNVG?

  The L3Harris Ground Panoramic Night Vision Goggle (GPNVG) features a guaranteed minimum FOM of 2376+.

• How does the L3Harris GPNVG perform in low-light conditions?

  The GPNVG excels in low-light conditions thanks to its high Signal to Noise Ratio (SNR) and low Equivalent Background Illumination (EBI), ensuring clear images even in minimal light.

• What is the field of view provided by the L3Harris GPNVG?

  Unlike traditional night vision goggles that offer a 40° field of view, the L3Harris GPNVG offers an expansive 97° field of view.

• Is the L3Harris GPNVG waterproof?

  Yes, the GPNVG is waterproof and submersible up to 66 feet, making it suitable for a variety of operational environments.

• How long does the battery last on the L3Harris GPNVG?

  The GPNVG operates for approximately 30+ hours on a single battery pack, providing extended usability in the field.

• Can the L3Harris GPNVG magnify images?

  The GPNVG 18 Night Vision Goggles has a 1x magnification, designed for optimal situational awareness without altering the natural perception of distance.

• What is the significance of the Halo effect in night vision?

  Halo refers to the bright circle around lights when viewed through the GPNVG-18 NVG. It’s a common trait of night vision optics and indicates exposure to a light source that is too bright, potentially affecting visibility.

• How wide is the L3 GPNVG 18 view?

  The GPNVG 18 Night Vision offers an unparalleled field of view, spanning across a wide 97 degrees. This significantly surpasses the traditional field of view of 40 degrees found in most night vision systems, providing users with almost triple the visibility range. This expansive GPNVG view is crucial for situational awareness during night operations, allowing users to see a broader panorama without the need to turn their head excessively.

• Where can I find the GPNVG 18 for sale and what is the GPNVG 18 price?

  You can find the L3harris GPNVG for sale on the Atomic Defense website. Detailed information as well as the GPNVG-18 price is also available on the website. Specializing in cutting-edge safety and tactical gear, Atomic Defense offers a range of night vision systems and accessories for military, law enforcement, and security personnel.

• What are 20UA intensifier tubes and how do they differ from other models?

  The term “20UA” refers to a high-performance night vision intensifier tube from L3Harris, designed for aviation use. These tubes have stringent quality standards for dark spots, allowing larger spots only in the outermost zone (Zone 3), ensuring a clearer image.

  Key Features of 20UA Tubes:

  • Strict Spot Tolerance: Larger dark spots (> .003 inches) are only allowed in Zone 3, ensuring high image clarity.

  • High Performance:

    • Center Resolution: 64 lp/mm minimum

    • Figure of Merit (FOM): 1792 minimum

    • Halo: 1.0 maximum

    • Equivalent Background Illumination (EBI): 2.5 maximum

  L3 20UA tubes offer excellent image quality with minimal imperfections, making them ideal for aviation and other high-demand applications.

• Why is it not recommended to use rechargeable batteries in L3 GPNVG?

  Rechargeable batteries are prone to leaking, which can cause significant damage to the sensitive electronics and components within night vision goggles. This leakage can result in malfunctions or even complete failure of the device.

• What type of batteries should I use for my L3 GPNVG?

  It is highly recommended to use lithium batteries for night vision goggles. Lithium batteries are more stable and less likely to leak, ensuring the longevity and optimal performance of your night vision equipment.

• What should I do if my GPNVG-18 doesn't turn on?

  If your GPNVG-18 are not turning on, follow these steps:

  1. Check the Battery Orientation: Ensure that the batteries are inserted correctly. The direction of the batteries must match the device’s specified orientation.
  2. Replace with New Batteries: If the batteries are inserted correctly and the device still does not power on, replace them with brand new batteries. Often, the issue is due to depleted batteries.

• What are dark spots on intensifier tubes, and what are the different zones?

  Dark spots are small black dots you might see when looking through night vision goggles (NVGs). They occur because of tiny imperfections in the intensifier tube, which helps amplify light to let you see in the dark. These spots don’t usually affect how well you can see. Intensifier tubes have three zones:

  1. Zone 1: The central area where you look the most. It’s the clearest part.

  2. Zone 2: The middle ring around Zone 1. This zone might have a few more imperfections.

  3. Zone 3: The outer edge. This zone can have the most imperfections, but it doesn’t affect your view much because it’s on the edges.

  The fewer dark spots an NVG has, the higher its quality and price. NVGs with almost no dark spots are typically more expensive because they have better intensifier tubes. However, a few dark spots are normal, and as long as they don’t block your view too much, your NVGs should work just fine.
