The COTI is a Clip-On Thermal Imager that easily attaches to existing night vision devices (NVDs) to add additional capabilities. The COTI enhances the functionality of currently fielded NVDs by adding a thermal overlay to the I² scene without modifying existing hardware. This addition of thermal imaging capability provides to two major benefits: Thermal detection capabilities while using NVDs and increased situational awarenes in extreme low light, no light, or foliated conditions where I² devices are limited. In addition, the COTI system contains a powerful internal micro-prcoessor that permits custom configuration of the unit. The variable user configuration enables the best mission centric performance. With a standard quick disconnect, the COTI interfaces to the AN/PVS-7, AN/PVS-14, AN/PVS-15, AN/PVS-18 and AN/PVS-23.

Low power consumption, optimal sensor technology and high-performance optics integrate seanlessly to provide state-of-the-art long-wave infrared technology. Since the COTI mounts on currently existing NVDs with a simple bracket, the clip-on technology allows increased capabilities without the need to refit helmets for special equipment. The small and lightweight design consumes very little power allowing extended use. Additionally COTI's waterproof and rugged construction can withstand the harshest environments.

When added to a standard I² system, the COTI enables the user to detect thermal sources and improve situational awareness. Even in pitch-black, no-light, adverse environmental conditions, recognition range extends dramatically. With the COTI the user is even able to see darkened openings and detect residual heat - situational awareness at the highest level.
