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): 2376 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 BNVD-1531?
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 BNVD-1531?
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 BNVD-1531 doesn't turn on?
If your BNVD-1531 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.
