Optical performance
Focal Length: With a focal length range of 18–275 mm, continuous zoom is supported, meeting imaging needs across various distances and scenes.
Aperture: The aperture is set to F5.5, which helps control the amount of light entering the lens to a certain extent and ensures image quality.
Detector compatibility: Compatible with 640×512 cooled detectors, fully leveraging detector performance to deliver high‑quality infrared imagery.
Operating spectral range: The operating spectral range is 3–5 μm, corresponding to the mid-wave infrared band. Image quality in this band generally surpasses that of the long-wave infrared (LWIR) band, offering distinct advantages when high requirements are imposed on detection range and temperature resolution.
Horizontal field of view: 30.6° at the wide end and 2.05° at the telephoto end, with the field of view adjustable to match changes in focal length.
Optical Coating: All internal surfaces are coated with high‑efficiency anti‑reflection films; the front surface can be equipped, upon request, with a highly durable anti‑reflection coating (e.g., DLC).
Mechanical properties
Focus/Zoom Mechanism: Employs an electric focus and zoom system, enabling remote control and automated operation.
Weight: With a total weight of just 280 grams, it features an ultra-compact design, making it ideal for installation in equipment with stringent weight requirements.
Physical dimensions: Measuring φ63.5 × 73 mm, it is compact and easy to integrate into various optoelectronic platforms.
Application scenarios
I. Security Surveillance and Border Control (border and coastline monitoring; airport and port security; urban complex‑environment surveillance).
II. Industrial Equipment Condition Monitoring and Fault Early Warning.
III. High-Precision Thermal Analysis in Research and Laboratory Settings (High-Temperature Process Monitoring; Fundamental Research on Thermal Imaging; Development of New Energy Technologies).
IV. Lightweight Applications of Drones and Mobile Platforms (Power and Photovoltaic Inspection; Disaster Emergency Response; Agricultural and Ecological Monitoring).
V. Intelligent Transportation and Fire Prevention.
