MKS Inc. has released the Ophir SupIR-X 15-300mm f/4 Mid-Wave Infrared (MWIR) Continuous Zoom Lens at ADEX Seoul.
The next-generation optical solution is specifically engineered for 10 µm SXGA (1280 x 1024 pixels) detectors, aiming to improve clarity, precision, and operational reach for Intelligence, Surveillance, and Reconnaissance (ISR) missions across air, land, and sea.
MKS, a global provider of enabling technologies, states that the SupIR-X 15-300mm f/4 lens is built on a proven legacy but designed to meet modern ISR needs by fully unlocking the thermal imaging performance of 10 µm SXGA detectors.
The lens provides high-performance MWIR imagery, featuring low distortion, Line-of-Sight (LOS) stability, and boresight retention. It is fully compatible with the existing Ophir extender ecosystem, allowing the focal length to scale up to 1200mm. This capability is cited to extend vehicle detection ranges beyond 26km while maintaining a constant f/4 aperture. An integrated mechanical shutter is also included to ensure consistent image quality in dynamic environments.
Dr. Kobi Lasri, General Manager of Ophir Optics, said, “Optical precision and reach have long been a challenge for ISR missions. The SupIR-X 15-300mm f/4 lens represents a generational leap in MWIR zoom technology. Designed specifically for SXGA 10 µm detectors and integrated with the Ophir long-range extender suite, it empowers ISR electro-optics systems with the clarity, resolution, and range required for today’s evolving missions.”
The SupIR-X 15–300mm f/4 lens is optimized for 10 µm SXGA MWIR detectors in the 3.6-4.2 µm and 3.6-4.9 µm spectral bands. It delivers a horizontal Field of View (FOV) from 45° down to 2.4° with high spatial resolution and low distortion across the full image.
Key specifications include a high transmission of 92% (high durability), high-speed motorized focus in less than one second, and fast zooming in eight seconds or less. The integrated shutter supports mechanical Non-Uniformity Correction (NUC), and an extended Back Focal Length (BFL) simplifies system integration. Compatibility extends to 19.4mm and 20.5 mm cold shield height detectors, supporting a wide range of leading MWIR sensors. The lens is described as rugged yet compact, measuring 93.4 x 132mm, weighing approximately 1kg, and able to withstand operating conditions from -32°C to +80°C with IP67 front element sealing.
Configurations utilizing the Ophir optical extender ecosystem allow focal lengths to scale from 30mm up to 1200 mm, with options including 30-600mm, 35-690mm, 45-900mm, and 60-1200mm. These configurations enable vehicle detection ranges of more than 26km under standard operational conditions. Available in high durability and hard carbon coating configurations, the SupIR-X lens is engineered for harsh environments.
With motorized focus and zoom, rapid response, and ruggedized mechanics, it is intended for use in border and homeland security, long-range ISR, Counter-Unmanned Aerial System (C-UAS) operations, critical infrastructure protection, coastal and maritime surveillance, law enforcement, and civil defense. The SupIR-X 15–300mm f/4 MWIR zoom lens is currently available.
