MKS Introduces Ophir® SWIR 50-1000 mm f/5.5-9.5 Continuous Zoom Lens

Andover, MA, April 28, 2026 – MKS Inc. (NASDAQ: MKSI), a global provider of enabling technologies that transform our world, announces at SPIE Defense + Security 2026 the Ophir® SWIR 50-1000 mm f/5.5-9.5 continuous zoom lens, a long‑range imaging solution engineered for the most demanding tactical and surveillance applications.

Designed for 10 µm SXGA, 15 µm VGA, and 10 µm VGA SWIR detectors, the lens operates across the full 0.6–1.7 µm spectral range, delivering sharp, high‑contrast imagery in low-visibility conditions for long‑range Intelligence, Surveillance, and Reconnaissance (ISR) missions and laser detection tasks across air, land, and maritime platforms.

The Ophir SWIR 50–1000 mm lens delivers vehicle detection ranges exceeding 35 km. Its broadband sensitivity enables detection and tracking of key laser wavelengths at 850 nm, 905 nm, 1064 nm, and 1550 nm. The optical design maintains focus and line‑of‑sight (LOS) stability throughout the zoom range, ensuring consistent image clarity in degraded visibility and during rapid transitions on stabilized multi‑axis payloads. An athermalized architecture preserves image quality across temperature variations, supporting reliable operation in harsh environments.

“ISR applications demand more signal, range, and integration flexibility,” said Dr. Kobi Lasri, General Manager of Ophir Optics Products. “To meet these needs the Ophir SWIR 50-1000 compact lens features excellent low‑light sensitivity and precise long‑range discrimination. Combined with 0.6–1.7 µm broadband response, continuous zoom, ruggedization, and near‑diffraction‑limited imaging, it enables confident detection, recognition, and identification across airborne, maritime, and ground ISR.”

The Ophir SWIR 50–1000 mm lens provides a horizontal field of view from 14.5° to 0.7°, enabling both wide-area situational awareness and precise long‑range identification in a single system.

With rugged construction rated for operation from –32 °C to +75 °C and an IP67‑sealed front element, the lens is engineered to withstand demanding field conditions. It measures Ø146 × 391 mm and weighs 3.6 kg.
