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 940 model with 940nm peak wavelength. The main advantage of the 940nm wavelength is that it is completely invisible.
