The AGM Sioux extra long-range infrared illuminators provide advanced image-intensified viewing capabilities to night vision devices, and is ideally suited for operations in little to no ambient light. The illuminator features adjustments for field of view divergence and output power, extending the capabilities of night vision device. One of the market’s most powerful infrared illuminators, the AGM Sioux comes equipped with the 18650 rechargeable battery and charger. The Sioux line includes the Sioux 850 model with 850nm peak wavelength and Sioux 940 model with 940nm peak wavelength. The 850 nm wavelength is standard for most night vision applications. The 850nm light source does produce a faint red glow at direct exposure, but otherwise it is not visible to the naked eye. The main advantage of the 940nm wavelength is that it is completely invisible.
Night vision devices rely on small amounts of ambient light to capture clear imagery, but if it is very dark, you can use the AGM Sioux940 Long-Range LED Infrared Illuminator to illuminate subjects in complete darkness up to 600 yards away, allowing night vision optics to produce a better image. Sharing the same features as the popular Sioux850, the upgrade in peak wavelength to 940nm on this model means that the IR LED is completely invisible to the human eye—ensuring complete stealth when strict light discipline must be observed.
Utilizing a powerful IR LED that outputs 800mW at 940nm peak wavelength, you have the option of adjusting the beam angle in a tight 4° spotlight to maximize its throw or a wide 35° flood light for performing tasks like scouting, navigating, or illuminating LZs and staging areas. A simple rotary tailcap switch enables you to toggle between power output intensities and ensures easy operation with a reduced risk of accidentally turning the light on—as can happen with many push-button switches. The light is powered by an included 18650 rechargeable battery with a battery cradle charger.
Designed to be used as a conventional handheld device or weapon mounted, the Sioux940 is lightweight at just 7.9 ounces and compact with a length of just 6 inches. To make it easy to install on your long gun or night vision scope, AGM includes a Picatinny/Weaver rail mount with three risers that allow you to raise the illuminator 10, 30, or 40mm above the rail so it will clear scopes with large objectives. The light is water and fog resistant to enable its continued use if the weather takes a turn for the worse.
