The COTI (Clip On Thermal Imager) by Optics1 gives warfighters "Predator"-style vision to better tag those terrorists and other threats; it adds thermal signals to to existing night-vision devices.

The human eye sees light in wavelengths between 400-700 nanometers, while a night-vision device is near the infrared range, around 900. The COTI's long-wave infrared technology is in the 8- to 10-micron range, allowing users to see through smoke, foliage, fog, rain and other conditions where standard devices provide only limited capability.
