Ophir Optronics, an MKS brand and a leader in optical solutions, offers cutting-edge IR continuous zoom lenses designed to provide unparalleled performance in Counter-Unmanned Aerial Systems (C-UAS) applications.

These lenses are optimized for long-range detection, precise identification, and reliable tracking of small unmanned aerial systems (sUAS), ensuring superior operational effectiveness in the field.

The rapid proliferation of drones over the past decades has introduced significant security challenges for both civilian and military sectors. This escalation in potential threats has spurred the development of sophisticated C-UAS technologies aimed at detecting, identifying, and neutralizing these risks. Among the leading solutions, infrared (IR) thermal imaging plays a crucial role, especially when integrated into multi-sensor C-UAS platforms.

Ophir’s IR continuous zoom lenses offer advanced optical design and rugged construction making them an asset to modern defense systems tasked with countering the growing threat of sUAS. By providing precise, long-range detection and identification capabilities, these lenses enhance the operational readiness and effectiveness of military and security forces.

Delivering exceptional image clarity with a Modulation Transfer Function (MTF) close to the diffraction limit ensures crisp, clean imagery across the entire zoom range, facilitating accurate identification and tracking. The precision optics maintain focus throughout the full zoom capability, allowing seamless transitions between wide and narrow fields of view without losing sight of the target.

With capabilities extending beyond 8 kilometers, these lenses are engineered for long-range engagements, providing operators with the ability to detect and identify threats from significant distances. This extended reach is crucial for early threat detection and effective countermeasures.

Built to endure the most challenging conditions, Ophir’s lenses are ruggedized and compliant with US and European military standards for temperature, shock, vibration, and environmental sealing.
