The Challenge:

L3 Insight Technology’s PVS-14 Night Vision Device (NVD) is the most versatile Mil-Spec monocular in the world. It can be mounted on a helmet to use with either the left or right eye or used as a hand-held device. It comes with the highest un-filmed 2376 FOM white phosphor tubes available.

There is a large inventory of standard green phosphor PVS-14s in the military today, but L3 Insight Technology’s improved white phosphor technology allows for greater target detection and recognition.

Lastly, some of these units have been in the field for 12+ years and may be in disrepair, missing parts from the original kits or beyond their service life.


The Solution:

ADS and L3 Insight Technology worked together to offer customers an easy way to replace the PVS-14 green phosphor tubes with new white phosphor tubes.


White phosphor decreases eye strain, is easily integrated with other technologies (thermal-fused, etc.), and ultimately increases survivability by allowing warfighters to complete their mission accurately and effectively.


  • Lowlight and nighttime maneuvers appear more natural in black and white, with added contrast detail in shapes and shadows providing the operator with more visual information for assessment and acquisition.
  • White phosphor offers various shades of intensity between black and white (over black and green), resulting in better contrast and depth perception.
  • There is a marked difference in operational time going from approximately four hours for eye strain with green phosphor to 10 hours for eye strain with white phosphor.

White Phosphor Tubes vs. Green

Replacement White Phosphor Tube


There’s no question as to why a command or unit wouldn’t want to replace their green phosphor tubes with white phosphor. For DoD, the issue in readily replacing night vision devices comes down to budget or the color of money. It’s much easier to get approval for a sustainment upgrade on a product because it’s considered a modification as opposed to buying a new product.

How to buy:

  • Customers can order just the white phosphor tubes and replace them at the Unit level.
    • This would essentially give them a new PVS14 in white phosphor around the same cost of ordering a new PVS14.
  • Customers can send their used units back to L3 Insight Technology for upgrading.
    • They can choose from either a repairing of any minor defects or opt for a complete re-kitting.
    • The cost is actually equivalent to or cheaper than the unit purchasing the tubes while basically getting a new night vision device.

Research Design & Development Testing Fielding Sustainment

The L3 Night Vision Device sustainment upgrade allows the customer to more readily enhance their legacy systems with white phosphor tubes, thus enhancing warfighter performance.

The customer will essentially get back a brand new, fully kitted PVS-14 in white phosphor for less than replacing the tubes, will get the budget approved faster, and will receive the product in-hand sooner than going through the stock system.

Available for purchase through: 

ADS can provide a unique part number that allows the customer to purchase the white phosphor tubes or obtain an RMA and send to the manufacturer for replacement.
