The 50mm F/2.0 SWIR lens is a high-quality optical component designed for short-wave infrared (0.9–2.5µm) imaging systems. Built with ZnSe materials, it delivers excellent transmission and stable performance, making it a reliable choice for demanding thermal and scientific applications.
Unlike MWIR or LWIR optics, SWIR technology works with reflected light rather than thermal emission. This unique property provides image clarity that closely resembles visible-light cameras, while revealing details invisible to traditional infrared。
Bright F/2.0 Aperture – Enhances signal capture for low-light or long-range observation.
High Transmission Efficiency – Average transmittance above 80%, optional AR coating available.
Temperature-Stable Performance – Works consistently from –40 °C to +80 °C without focus shift.
Compact and Versatile – Lightweight structure designed for integration into drones, cameras, and monitoring equipment.
