The fixed SWIR lenses deliver high‑resolution infrared imaging. Unlike heat‑detecting thermal cameras, they capture reflected light to see through fog, haze, smoke, plastics and silicon.
With fixed‑focus non‑zoom design, they ensure stable, repeatable performance and long‑term durability. Manual locking screws keep settings steady for surveillance and industrial automation.
Perfect for agricultural moisture testing, semiconductor inspection, night‑time border monitoring and other AI‑driven vision applications.
