The 25/70mm F0.95/1.1 Dual-FOV Infrared Lens is a high-performance long-wave infrared (LWIR, 8–14μm) optical system designed for both 12μm and 17μm uncooled detectors. Featuring two selectable focal lengths—25mm wide-angle and 70mm narrow-angle—this lens allows users to quickly switch between wide and narrow fields of view.
This dual-mode design offers unmatched operational flexibility: wide-angle mode enables rapid scanning and situational awareness, while narrow-angle mode provides focused detail and precision measurement. Built with durable materials and optimized coatings, it delivers stable thermal transmission and reliable imaging performance in challenging environments.

Dual-Field-of-View Design (25mm / 70mm) – Wide and narrow FOV in one lens
Large Apertures (F0.95 / F1.1) – High sensitivity and clear thermal imagery
Uncooled Detector Compatibility – Optimized for both 12μm and 17μm sensors
Cost-Effective Integration – One lens provides the function of two, reducing system complexity
Wide FOV (25mm): Quickly scan disaster areas, penetrate smoke and darkness, and locate fire sources or trapped individuals.
Narrow FOV (70mm): Focus on identified targets for precise confirmation—analyzing victim posture or fire hotspots for effective rescue planning.
Wide FOV (25mm): Conduct global temperature scans of large-scale equipment (e.g., power grids, chemical reactors) to detect anomalies.
Narrow FOV (70mm): Zoom in on abnormal zones for accurate temperature measurements and detailed fault analysis.
Wide FOV (25mm): Perform wide-area search, terrain observation, and flight path planning.
Narrow FOV (70mm): Maintain stable tracking and reconnaissance of specific targets of interest.
Q1: Is the lens suitable for uncooled detectors only?
Yes, this model is specifically designed for uncooled detectors (12μm / 17μm). For cooled systems, other configurations are available.
Q2: Does the dual-FOV design increase system weight significantly?
No, it is optimized to balance functionality with compact size, making it suitable for UAV payloads and portable equipment.
Q3: Can this lens be customized?
Yes. Custom housing interfaces, coatings, and environmental protections can be provided according to application requirements.
