Product Introduction
The LWIR series lenses are prime and zoom lenses specially designed for LWIR band (8~12μm), compatible for conventional LWIR uncooled detectors, with near-diffraction limit performance. The products adopt unique optical technology and exclusive IR image and enhancement algorithm, and can meet the needs of various complex target scene applications. Characterized by high contrast, low distortion, compact structure and low power consumption, they are widely used in vehicle-mounted viewing, airborne pods, urban security monitoring, forest fire warning and other scenes. The products can conduct 24/7 monitoring in a variety of complex environment, with a wide monitoring range.
The production and development can be customized according to the client's requirements.
