OKS-5001-B21 is a high-performance F1.6 large-aperture M14 telephoto lens specially designed for digital night vision devices, night vision monoculars, goggles and low-light observation equipment. Adopting premium 6 all-glass optical design, it matches 1/2.8" CMOS sensor to deliver crisp high-definition details. The F1.6 large aperture provides excellent light-gathering ability, realizing clear imaging under extremely dark night environment without strong infrared illumination. 16mm telephoto focal length provides 25.8° diagonal narrow field of view, ideal for long-distance night observation, target recognition and wildlife monitoring. Ultra-low CRA below 4.5° ensures extremely uniform image brightness across the full frame, which is critical for consistent night vision image quality. Low F-Tan distortion -4.6% delivers natural undistorted image for accurate observation and distance judgment. Large Ø7.0mm image circle fully covers 1/2.8" sensor. Compact 37.5mm TTL and Ø16.0mm front barrel design fits most night vision device housings. Wide operating temperature from -40℃ to +85℃ with focus range 0.6m to infinity guarantees steady all-weather outdoor performance for night vision monocular, goggle, hunting observation and security low-light monitoring modules for mass OEM production.
