SWIR MAWL-CLAD – Now Even More Invisible IR Laser

Got IR Lasers and Night Vision? Well now there is something even more invisible than that. SWIR is a lower wavelength on the infrared spectrum. NIR (Near Infrared) is what most night vision sees and IR lasers are set to. NIR is 0.75–1.4 µm. SWIR is 1.4–3 µm. What does this mean? You cannot see it with a normal night vision device.

October 9, 2017 (Redmond, WA) –

B.E. Meyers & Co., Inc. is proud to announce the release of a new variant of the MAWL series of weapon aiming lasers and illuminators: the MAWL-CLAD (Covert Laser Aiming Device).

The MAWL-CLAD distinguishes itself from other MAWL variants through the inclusion of a Short-wave Infrared (SWIR) laser pointer. This laser is undetectable by most common Near Infrared (NIR) night vision systems and other visual augmentation sensors, but is compatible with a variety of SWIR systems (i.e. E-COSI) currently in use with Special Operations Forces.

The MAWL-CLAD retains the NIR wavelength diodes present in other MAWL models to provide both marking and illumination for its primary “IR” function mode. This NIR system is visible with most common night vision systems and provides users with an effective aiming, illumination, and signaling solution for almost any low-light/no-light scenario. With the MAWL-CLAD, users can now seamlessly transition between a full suite of NIR aiming and illumination modes and a SWIR laser pointer for aiming or signaling when necessary, making it compatible with all current night vision systems.

The MAWL-CLAD is part of a greater MAWL (Modular Aiming Weapon Laser) system that allows operators to shoot, move and communicate effectively. Its modular head includes a SWIR option (made possible through replacement of the standard green visible laser pointer found on the MAWL-DA and MAWL-C1+) that can be used interchangeably with any existing MAWL platform. This swap can be done while leaving the main housing attached to the weapon rail. Like the visible green laser on other MAWL models, the SWIR pointer on the MAWL-CLAD is coaligned with the NIR pointer, allowing it to be zeroed without a SWIR sensor.

The MAWL-CLAD allows us to take advantage of the modular design aspects of the MAWL system, and lets the end-user adjust between pre-boresighted, capability specific laser modules, as needed for special mission sets” said Matt Meyers, President of B.E. Meyers & Co. Inc. “With the increased number of SWIR sensors being fielded to Special Operations Forces, the MAWL-CLAD lets the operator choose between SWIR and NIR capability on the move, and also allows them to revert back to the VIS and NIR capability in a matter of seconds by switching to the MAWL-DA Head without detaching the main body of the laser, or losing zero.”

The MAWL-CLAD is the third variant in the MAWL family of weapon laser systems. For more information about the MAWL-DA, MAWL-C1+, and MAWL-CLAD, including product demonstrations and purchasing options, please contact the B.E. Meyers & Co. team at sales@bemeyers.com.

Mark Larue, at Big 3 East,  had mentioned that there is a concern that bad guys have been taking digital cameras and removing the hot mirror IR filter to spot IR lights and lasers. Since SWIR is a different and higher spectrum the MAWL CLAD should be invisible to that technology.


BE Meyers has made an SWIR head for their flagship MAWL laser unit. CLAD (Covert Laser Aiming Device)

All you need to do is swap heads and you have an SWIR capable laser device.

So if you cannot see SWIR with normal night vision, what can see SWIR spectrum? E-COSI is a clip on device that injects the SWIR image into night vision devices.

The Optics 1 Enhanced Clip-On SWIR Imager (E-COSI) is a multi-function device with replaceable display heads, allowing the SWIR image to be:

  • Injected into NVG, overlaying the SWIR image onto the NVG image
  •  Seen during the day with an optional see-through day optic (for See-Spot operations)
  • Exported to outside devices for external recording/monitor input

Night Vision Devices (NVDs) work well for target pointing and marking/identification, when used with Near-Infrared Laser Aiming and Illumination devices. Now, E-COSI increases the effectiveness of legacy and recently fielded NVDs by overlaying a SWIR image onto a night vision scene. E-COSI can be used to see laser markers and designators during day and night operations. Also, the Heads-Up Display capability provides real-time, geo-referenced navigation/route execution for dismounted soldiers, reconnaissance, scout/snipers, Navy fast boat drivers, and/or pilots.

Sort of like Google Glass augments your vision, the Enhanced Clip On SWIR Imager (E-COSI) super imposes the image into the field of view of night vision devices.

Here is an example of what clip on thermal looks like using night vision devices. While it is not the ECOSI it is similar to the ECOTI and you get the idea.

    Interesting – photonics of night vision goggles is slowly creeping into more parts of the EM Spectrum. a NVG is at its heart an amplifier. Transistors are like amplifiers that can be used as switches. Why don’t we have optical logic circuits yet that compliment our electronic circuits? you could have data paths that cross each other (unlike electrical paths that need to be insulated from each other by a nonconductive layer) and achieve higher compute density in your computing products.

      if we reverse the polarity on the phase conduits, it should deionize the Dilithium crystals in the imaging tube and allow the away team to see the Klingons through…

      • Michael R. Zupcak

        Make it so.

    • KidCorporate

      Oh, we have ’em. They feature heavily in telecommunications equipment already and have many military applications that are still mostly classified.

      • Samuel Millwright

        Ding ding

    • James Bridges

      A quick Google search showed several papers on optical logic Gates and amplifiers. As mentioned they are mostly Telecom centric.

      We do have optical devices… How do you think the internet and cable gets to your house…? (edit, this is misleading, optical cable is the big lines across countries and states and sometimes to neighborhoods. They sometimes go to houses. but it’s usually copper wire.)

      What the US does not have is optical cable to the home. We were first or close to the first country to install copper cable nationwide so its too costly to replace all that copper with optical systems. It is really hard to get a company to replace it and the government has too many other areas of pork to pay into to do it.

      As for mixed systems… They are stupid. It is like mixing a thousand generation electrical system with a twentieth or fiftieth generation optical system. In other simpler terms. One is playing with atoms, the other is playing with the big legos.

      We will eventually move to pure optical systems or something totally different but copper is going away. It is just super mature and hard to compete with since everything has already been polished to almost perfection.

      • Marcus D.

        When copper gets scarce, they can strip the lines and sell it all to Lake
        City and Lehigh for bullets and jackets, thus paying for the cost of putting up the lighter, faster, fiber optic cables. Well, maybe.

    Im not smart enough to understand this. 🙁

      IR lasers are invisible to the naked eye. You can only see them with night vision. SWIR Lasers are invisible to night vision. You need a special device to see SWIR.

  • Mr._Exterminatus

    This is definitely interesting.

    I don’t know what sort of hellscape requires operating with NVGs in a 122+ degree climate, but I do know I never want to go there

    • Renato H M de Oliveira

      Temperatures in Mideast can go past tge 122 °F sometimes.

        …and that’s in the shade.

    Easy to get confused here since there’s an error in the article.

    The article states that the WAVELENGTH is longer – “NIR is 0.75–1.4 µm. SWIR is 1.4–3 µm”, but then it says: “…since SWIR is a different and higher spectrum”. If SWIR is in a higher spectrum (frequency) it has a SHORTER wavelength, not longer than N-IR. So it’s actually a LOWER spectrum, not higher.

    The “short wave” name is confusing here since SWIR is actually being compared to Mid-wave and long-wave IR and NOT to Near IR. So, the order goes (in INCREASING wavelength and DECREASING frequency):

    Near-IR –> SW IR –> Mid-wave IR –> Long-wave IR

    Near is so named because it’s very close to the visual range and therefore a higher frequency than all of them. So this new gear is invisible to most NV gear since the frequency is too low to be detected.

      Thanks for the clarification. I will edit the article to reflect the info.
