SWIR 50–1000mm continuous zoom lens for advanced long-range imaging and tactical detection

MKS Ophir's SWIR 50–1000mm f/5.5–9.5 Continuous Zoom Lens is engineered for defense ISR payloads requiring extended-range target observation, laser event awareness, and stable imaging performance across changing tactical conditions.

Built for 10 μm SXGA, 15 μm VGA, and 10 μm VGA SWIR detectors, the lens operates across the 0.6–1.7 μm band, supporting high-contrast short-wave infrared imaging for air, land, and naval surveillance architectures. Its broadband response enables detection and tracking of key defense laser wavelengths, including 850 nm, 905 nm, 1064 nm, and 1550 nm, making it suitable for long-range reconnaissance, laser designation monitoring, and threat identification workflows.

With a 50–1000 mm continuous zoom range, the lens provides both wide-area scene acquisition and narrow-field inspection, delivering a horizontal field of view from 14.5° to 0.7°.

The optical design maintains focus and line-of-sight alignment throughout zoom transitions, supporting persistent tracking without image instability or frequent refocusing. An athermalized construction helps preserve image quality across demanding temperature shifts, while a rugged field-ready housing enables operation from –32 °C to +75 °C with an IP67-sealed front element. Capable of vehicle detection up to 35 km, the SWIR 50–1000mm lens is well suited for for border surveillance, naval observation, airborne ISR, and fixed-site defense security systems.
