L3Harris Gen 3 Unfilmed White Phosphor Image Intensifier Tube
The L3Harris Gen 3 Unfilmed White Phosphor image intensifier tube is a premium night vision intensifier designed for users who prioritize performance in extremely low-light environments.
L3Harris Unfilmed technology is known for excellent low-light performance, high signal-to-noise ratios, and strong overall image quality. These tubes are a popular choice for professional users and serious night vision enthusiasts operating under challenging conditions such as heavy tree cover, limited ambient illumination, and moonless nights.
These are brand-new L3Harris image intensifier tubes and include the applicable factory data sheet and a 2-year warranty.
QDEF Hand-Selected Tubes
Every image intensifier tube sold by Quad Defense is hand-selected for our customers. We do not simply pull a tube from inventory based on FOM and ship it.
Our team reviews the available tube specifications and cosmetics and will work directly with you to select a tube based on the characteristics that matter most for your intended use and personal preferences.
If you have specific requirements for SNR, EBI, halo, gain, resolution, FOM, or tube cosmetics, contact us before ordering. We'll review current inventory and help identify the best available tube for your requirements.
For binocular builds, QDEF also selects and pairs tubes with attention to their specifications and overall image characteristics to create a consistent binocular night vision system.
L3Harris Unfilmed Technology
L3Harris Unfilmed image intensifiers are designed to deliver strong performance when available light becomes extremely limited. Removing the traditional ion barrier film allows more electrons to reach the microchannel plate, contributing to the low-light performance for which L3Harris Unfilmed tubes are known.
The result is an intensifier platform well suited for users who place a high priority on performance under demanding ambient-light conditions.
MX-11769 Manual Gain
The L3Harris MX-11769 format incorporates a variable-gain power supply, allowing compatible night vision systems to provide manual brightness control.
When installed in a compatible manual-gain housing, the user can adjust image brightness to better suit changing ambient-light conditions and personal preference.
Available Performance Levels
L3Harris image intensifier availability varies, but QDEF commonly offers tubes across several performance ranges:
- 1800β2200 FOM
- 2200β2400 FOM
- 2400+ FOM
FOM should not be considered by itself. Two tubes with similar FOM can have different SNR, resolution, EBI, halo, gain, and cosmetic characteristics. QDEF evaluates the complete specification set when helping customers select a tube.

Understanding Tube Specifications
When comparing image intensifier tubes, consider the complete specification set rather than focusing exclusively on FOM.
- SNR (Signal-to-Noise Ratio) β an important indicator of image quality as available light decreases.
- Resolution β measured in line pairs per millimeter (lp/mm) and describes the tube's ability to resolve fine detail.
- FOM (Figure of Merit) β calculated from SNR and resolution and useful as a general performance reference.
- EBI (Equivalent Background Illumination) β represents background output generated by the tube and becomes particularly relevant under extremely low-light conditions.
- Halo β describes the visible bloom surrounding bright points of light.
- Gain β describes the amount of amplification produced by the image intensifier.

QDEF COMPLIANCE // U.S. EXPORT CONTROL
Export &
ITAR Compliance
Certain products, components, technical data, and services offered by Quad Defense may be controlled under United States export-control laws and regulations.
These requirements may include the International Traffic in Arms Regulations (ITAR), the Export Administration Regulations (EAR), or other applicable U.S. laws and regulations.
Customers are responsible for understanding and complying with the export-control requirements applicable to the products or information they purchase, receive, transfer, resell, or otherwise provide to others.
Do not export, re-export, transfer, release, or provide controlled products, technical data, or services to a foreign person, foreign destination, or unauthorized end user without first determining whether U.S. Government authorization is required.
This includes transfers that may occur inside the United States when controlled technical data or other controlled items are released to a foreign person.
What Is ITAR?
The International Traffic in Arms Regulations are administered by the U.S. Department of State's Directorate of Defense Trade Controls (DDTC).
ITAR governs defense articles, defense services, and related technical data identified on the United States Munitions List, as well as certain exports, temporary imports, reexports, retransfers, and other controlled transactions.
Not every product sold by Quad Defense is necessarily ITAR-controlled. Export classification depends on the specific product, component, technology, technical data, and transaction.
Night Vision & Related Equipment
Night vision products and related equipment may be subject to U.S. export-control restrictions depending on their classification, configuration, technical characteristics, origin, and intended destination or end user.
Some products may fall under ITAR jurisdiction while others may be controlled under the Export Administration Regulations or another regulatory framework.
The absence of an βITARβ label on a product page should not be interpreted as confirmation that the product is unrestricted for international transfer.
Who May Receive Controlled Items?
Export-control rules can restrict who may receive certain products, technical data, or defense services.
ITAR distinguishes between U.S. persons and foreign persons. The applicable regulatory definitions should be used when determining whether a particular transfer or release requires authorization.
Citizenship alone should not be used as the sole test for every export-control determination.
Authorization May Be Required
Depending on the item and circumstances, U.S. Government authorization may be required before a controlled product or technical data may be:
- Exported from the United States
- Re-exported from one foreign country to another
- Retransferred to a different end user or end use
- Released or provided to a foreign person
- Sold or transferred to another party for a different destination or purpose
- Used to furnish a controlled defense service
Applicable licenses, agreements, exemptions, exceptions, or other authorizations must be determined before the transaction occurs.
Resale Does Not Remove Export Restrictions
Purchasing a product from Quad Defense and later reselling or transferring it does not eliminate applicable U.S. export-control restrictions.
Customers who resell controlled products are responsible for ensuring that subsequent transfers comply with applicable export-control laws, end-user restrictions, destination restrictions, licensing requirements, and other regulatory obligations.
Where appropriate, downstream purchasers should also be informed that the product may be subject to U.S. export-control restrictions.
Technical Information May Also Be Controlled
Export controls may apply not only to physical hardware but also to certain technical information associated with controlled products.
Depending on its content and classification, controlled technical data may include certain detailed information relating to the design, development, production, manufacture, assembly, operation, repair, testing, maintenance, or modification of controlled defense articles.
Quad Defense may therefore limit the distribution of certain technical information or documentation when necessary to comply with applicable export-control obligations.
