Elbit vs L3 Harris Night Vision Tubes: Which Is Actually Better?

Who Makes Gen 3 Night Vision Tubes in the U.S.?

There are exactly two manufacturers of Gen 3 image intensifier tubes approved for U.S. military procurement:

• L3 Harris Technologies Formerly Litton, then Northrop Grumman Electro-Optics, L3, and finally L3 Harris, which is ironic because Harris brings parts of what was originally ITT Night Vision into the L3 family.
• Elbit Systems of America, started as ITT Night Vision. Was split off as Exelis, then was acquired by Elbit, an Israeli defense company. To keep things legal under ITAR, Elbit Systems of America was formed as a separate, supposedly "self controlled" entity.

Both are American companies with ITAR-controlled manufacturing. Both have supplied U.S. military procurement for decades, and both built to the OMNI-VII and OMNI-VIII specification floors. OMNI-VIII is effectively dead for new production at this point — today, both manufacturers sell primarily by tube model. The OMNI specs are still the underlying military baseline these tubes trace back to, but tubes available commercially, especially "commercial" tubes, are often mil-spec drop-outs. It's uncommon, but not impossible, to come across a tube that looks like a screamer until your eyes hit something you think must be a misprint.

It is always better to know who the manufacturer is on your tube. That said, if you just want night vision "cheap cheap cheap" then you may end up with a tube that has no tube sheet and no sticker. You would literally have to disassemble the tube itself to know where it came from. Hey, if it works and saved you enough money to be able to afford something you could not otherwise, then stop your whining. Also, don't be surprised if the government calls looking for their stuff back. Life comes with choices and sometimes consequences. Much as we love a great deal as much, or maybe more, than the next guy, Adams Industries now provides manufacturer and spec documentation with every new tube we sell.

You've probably heard by now, but just in case you haven't: Elbit sells "Thin Film" tubes and L3 Harris offers "Filmless" tubes.

The Core Technical Difference: Film vs Filmless

The most meaningful technical distinction between Elbit and L3 Harris tubes is the ion barrier film on the microchannel plate (MCP). This holds at every grade level, not just Aviation Grade:

Removing the ion barrier film from the MCP improves how many electrons actually get multiplied. More electrons means higher signal, which is why filmless tubes run slightly higher SNR and slightly lower EBI and halo than thin-film tubes, across the board, not just at the top grade.

The darker it gets, the bigger the gap between filmless and thin-film. In extreme low light, filmless tubes hold brightness and contrast better than thin-film tubes. In moderate light, both perform close enough that most users won't notice a difference. Grade determines the overall performance ceiling; film vs filmless determines how that tube behaves as conditions get darker.

The tradeoff: without the protective film, the MCP is more vulnerable to damage from sustained exposure to bright light. That's why filmless tubes always use autogating, an electronic circuit that rapidly cuts off gain when the image intensifier detects a bright source. Modern autogating in both manufacturers' tubes handles this well in real-world tactical environments.

Image Characteristics: What Operators Notice

The operator preference split is roughly 60/40 L3 Harris among U.S. SOF operators who have access to both, not because Elbit is worse, but because L3 Harris filmless tubes consistently run slightly higher SNR and lower EBI/halo across the board, and that edge is most noticeable in the darkest conditions operators actually work in. For most civilian and law enforcement uses, the gap is not operationally significant.

Where the Difference Actually Matters: Light Conditions, Not Grade

The old way to frame this comparison was by grade: Aviation or A Grade supposedly, Professional and Field Grade, or B Grade and down, supposedly not. That's not right. Grade sets the overall performance ceiling of a tube regardless of manufacturer. Film vs filmless is a separate axis: it determines how a tube performs as light drops, and that holds true whether you're comparing two Aviation Grade tubes or two Field Grade tubes.

If you're buying for demanding low-light use at any grade, the filmless design's edge is real. If you're buying for property security, hunting, range use, or general outdoor recreation where you're rarely operating in the darkest conditions, both manufacturers' tubes will serve you well and you likely won't perceive a meaningful difference.

White Phosphor: Does Manufacturer Matter More?

White phosphor tubes are available from both manufacturers. In white phosphor, the tonal differences described above largely disappear. Both manufacturers produce tubes that render a clean grayscale image. The filmless vs thin-film SNR/EBI/halo differences still apply, and the same low-light rule still holds, but the "warmer/cooler" tonal debate becomes irrelevant.

Adams Industries stocks Aviation, Professional, and Field Grade Gen 3 tubes from both L3 Harris and Elbit Systems, filmless and thin-film, green and white phosphor. We do it all.

Which Should You Actually Buy?

1. For 90% of the world, it's all determined by budget and everything in 2-6 does not apply.
2. Determine your grade first. Aviation Grade for serious tactical or precision use. Professional Grade for everything else. This matters more than manufacturer.
3. Decide on phosphor. White phosphor is the right call for most buyers who can afford it.
4. Think about the darkest conditions you'll actually use it in. If you regularly operate in extreme low light, filmless (L3 Harris) has a real, consistent edge at any grade. If you rarely push into the darkest conditions, this stops mattering much.
5. Otherwise, take whatever manufacturer has better availability and price at the moment. You will not regret it.
6. Get the spec sheet. Always, if possible. Back to #1: if you want-need night vision and you're on a budget, then maybe you cannot afford the piece of paper. The individual tube's measured SNR, EBI, and FOM matter more than which manufacturer's name is on the label.

Frequently Asked Questions

Is it true that the military only uses L3 Harris tubes?

No. The U.S. military has procured Gen 3 image intensifier tubes from both L3 Harris and Elbit Systems under competitive contracts for years. Unit-level mix varies by procurement cycle and contract award. SOCOM has used both manufacturers. The "military only uses L3" narrative is a marketing position, not procurement reality.

What does filmless actually mean for the average buyer?

Filmless means the ion barrier film has been removed from the microchannel plate. This increases electron transmission and produces slightly higher SNR and slightly lower EBI and halo than a thin-film tube, at any grade level. The practical difference shows up most in extreme low light, where filmless tubes hold brightness and contrast better. In moderate light, most users won't notice it. The tradeoff, more careful autogating management, is handled automatically by modern device electronics.

Are L3 Harris filmless tubes worth the premium over Elbit thin-film?

If you regularly operate in extreme low light, yes, the filmless advantage is real and consistent regardless of grade. For general tactical use, patrol, hunting, and property security where you're rarely in the darkest possible conditions, an Elbit thin-film tube performs excellently and is often more readily available. Adams Industries stocks both, and we can help you choose based on your specific lighting conditions.

L3Harris vs Elbit: which night vision tube is better?

Neither is universally better; they're built to different tradeoffs. L3 Harris filmless tubes hold brightness and contrast slightly better in extreme low light. Elbit thin-film tubes perform excellently in general tactical use and are often more readily available. Grade matters more than manufacturer: an Aviation Grade Elbit tube beats a Professional Grade L3 Harris tube. Adams Industries stocks both and can match a tube to your actual operating conditions.

Where can I buy L3 Harris or Elbit night vision tubes?

Adams Industries sells both L3 Harris and Elbit Gen 3 image intensifier tubes directly, individually or built into a complete unit. See current inventory and grades on our image intensifier tubes page.
