The LRF0815C laser rangefinder module is a high-performance, eye-safe laser distance sensor designed for precise distance measurement across various target sizes. Operating at a wavelength of 1535nm, it complies with Class I eye safety standards (IEC 60825-1), ensuring safe use in diverse environments. The long-range 1535nm LIDAR module features a narrow divergence angle of ≤0.35 mrad and a receiving field of view (FOV) of ~2.0 mrad, enabling accurate detection of targets ranging from large structures (4 m × 6 m) at distances up to 12,000 m to smaller objects like drones (0.2 m × 0.3 m) at 1,500 m. With a ranging accuracy of ±2 m and a resolution of ≤30 m, the LRF0815C high-precision 1535nm laser module supports multi-target detection (up to 3 targets) and operates at frequencies from 0.5 to 10 Hz. It boasts a precision rate of ≥98% and a low false alarm rate of ≤1%. The compact and lightweight design (≤175 g, 65 mm × 46 mm × 86 mm) and wide operating temperature range (-40 to +70 °C) make it suitable for integration into various systems. This compact 1535nm rangefinder module is ideal for defense, UAVs, and industrial applications requiring reliable long-distance ranging in extreme environments. Powered by DC12 V, it consumes minimal energy (≤3 W peak) and communicates via TTL interface, offering reliability and efficiency for demanding applications.
