Optical Performance

Focal Length and Zoom ： Focal length range of 40–825mm, supporting 21x optical zoom to cover observation needs from wide-angle to ultra-long-distance views. The aperture is fixed at F4.0, ensuring sufficient light intake while optimizing image quality.

Probe compatibility: Compatible with 640×512×15μm cooled detectors, this solution fully leverages the detector's high sensitivity and resolution, making it ideal for low-light or challenging environmental conditions in thermal imaging applications.

Spectrum and Field of View: The working spectral range is 3–5 μm (mid-wave infrared band), with a horizontal field of view ranging from 14.4° at the wide-angle end down to 0.67° at the narrow-angle end, enabling precise identification—from broad-scanning applications to accurate targeting of distant objects.

Optical Coating: All internal surfaces feature a highly efficient anti-reflective coating, while the front surface offers an optional diamond-like carbon (DLC) coating to enhance scratch resistance and durability.

 

Application scenarios

It can be widely used in 24/7 monitoring applications across various industries, including border defense, military units, public security, smart cities, water resources, transportation, railways, forest fire prevention, airports, cultural heritage sites, oil and petrochemical facilities, industrial and mining operations, factory campuses, livestock farms, and agricultural cultivation areas.
