MKS Announces New MWIR Zoom Lens For 10µm SXGA Detectors, Scalable Up To 1200mm Focal Length

Andover, MA - MKS Inc. (NASDAQ: MKSI), a global provider of enabling technologies that transform our world, has announced the Ophir® SupIR-X 15-300mm f/4 Mid-Wave Infrared (MWIR) Continuous Zoom Lens at ADEX Seoul. Purpose-built for 10 µm SXGA (1280 x 1024 pixels) detectors, this next-generation optical solution delivers unmatched clarity, precision, and operational reach for intelligence, surveillance, and reconnaissance (ISR) missions across air, land, and sea.

Built on a proven legacy and engineered for modern ISR needs, the SupIR-X 15-300mm f/4 lens fully unlocks the thermal imaging performance of 10 µm SXGA detectors. The SupIR-X lens delivers high-performance MWIR imagery with low distortion, line-of-sight (LOS) stability, and boresight retention. The lens is fully compatible with the Ophir extender ecosystem, scaling up to 1200 mm focal length, extending detection ranges beyond 26 km for vehicle targets while maintaining a constant f/4 aperture. An integrated mechanical shutter also ensures consistent image quality in dynamic environments.

"Optical precision and reach have long been a challenge for ISR missions," said Dr. Kobi Lasri, General Manager of Ophir Optics. "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."

Specifications

The SupIR-X 15–300mm f/4 lens, optimized for 10 µm SXGA MWIR detectors in the 3.6-4.2 µm and 3.6-4.9 µm spectral bands, delivers a horizontal field of view (FOV) from 45° (wide FOV) down to 2.4° (Narrow FOV) with high spatial resolution and low distortion across the full image. It provides high transmission of 92% (high durability) and features high-speed motorized focus (<1 sec) and fast zooming (≤8 sec). An integrated shutter supports mechanical non-uniformity correction (NUC), while an extended back focal length (BFL) eases system integration. The SupIR-X lens is fully compatible with 19.4 mm and 20.5 mm cold shield height detectors supporting a wide range of leading MWIR sensors. Rugged yet compact, it measures Ø93.4×132 mm, weighs approximately 1 kg, and withstands –32 °C to +80 °C operating conditions with IP67 front element sealing.

The new lens is compatible with the Ophir optical extender ecosystem, allowing focal lengths to scale from 30 mm up to 1200 mm. Available configurations include: 30-600 mm, 35-690 mm, 45-900 mm, and 60-1200 mm, enabling vehicle detection ranges of more than 26 km under standard operational conditions.

Mission-Ready Versatility

Available in high durability and hard carbon coating configurations, the SupIR-X lens is engineered for the harshest environments. With motorized focus and zoom, rapid response, and ruggedized mechanics, it is mission-ready for border and homeland security, long-range ISR, counter-UAS operations, critical infrastructure protection, coastal and maritime surveillance, law enforcement, and civil defense.
