Longwave infra objective lens assembly 50mm FL
Longwave infra objective lens assembly 50mm FL
Longwave Infrared (LWIR) lens is typically uncooled and therefore, has less sensitivity. It allows the user to see through dust or smoke, which makes them particularly valuable in certain environments and applications. The field of view of a lens depends mainly on the focal length and the detector size.
