BACKGROUND Drones’ proliferation in recent century raise potential security threats to both civilian and military entities. Such threats triggered to a new, rapidly emerging Counter-Unmanned Aerial Systems (C-UAS) technologies. Its mission is to detect, identify and disable such threats. Infrared (IR) based systems, or IR imaging combined in such multi-sensor types of systems, is a prevalent technology enabling detection, identification and tracking the small unmanned aerial system (sUAS). Ophir designs and manufactures precise, long-range IR continuous zoom lenses for integration into premier C-UAS platforms. Ophir lenses give the C-UAS the best advantage in both identification and acquisition / targeting capabilities.
