Cooled midwave infrared (MWIR) cameras have long held a tactical advantage over uncooled longwave infrared (LWIR) cameras in many airborne and ground-based intelligence, surveillance, and reconnaissance (ISR) use cases. While cooled MWIR camera modules are highly sensitive, they are also more mechanically complex, larger, heavier, have a shorter mean time between failure (MTBF), require more power, and cost more than uncooled LWIR cameras. Many years of work both by the  US government and industrial organizations as part of a consortium called VISTA (Vital Infrared Sensor Technology Advancement) has led to advancements in High Operating Temperature (HOT) MWIR, uncooled LWIR and dual-color detector designs. The FLIR Neutrino™ LC is a new size, weight, and power (SWaP) optimized HOT MWIR camera that fits in the palm of your hand, uses less than four watts, and is suitable for missions previously dominated by uncooled LWIR cameras.
