Among the numerous night vision systems visible at Milipol, N-Vision exhibited the first commercially available thermal imaging system based on the most recent 12 µm technology. The latter allows reducing SWAP, size, weight and power, thanks to the smaller sensor size at the same level of definition.
Known as Atlas, the new product of the Minnesota-based company, is a surveillance system based on a single 640 x 512-pixel uncooled sensor installed behind a 50 mm f1.2 lens providing a 9° x 7° field of view. Images are shown on two 800 x 600-pixel high-resolution displays, the bi-ocular solution ensuring higher comfort to the operator in long-lasting missions. The refresh can be set at two rates, 9 Hz or 60 Hz, all settings being made via multi-functional buttons available over the system. Images can be recorded or sent via comms through a USB or analogue video output. Power is provided by three CR123 batteries hosted in a sealed compartment. The Atlas has a 2,250 meters detection range; it is 148mm long, 125 mm wide and 61 mm high, and weighs only 575 grams. N-Vision has already started producing the Atlas and the system is already in service with undisclosed customers.
