01 / Product introduction

Product introduction

A high-performance long-range ranging module built around a 1535 nm eye-safe erbium-glass laser. It reaches beyond 6 km against large structures and terrain while holding ±1 m accuracy, and its tightened ≤0.3 mrad divergence keeps the spot small enough to discriminate distant targets. At <55 g with an RS-422 interface, it integrates into civil UAV gimbals, handheld observation optics, industrial inspection equipment and smart security systems.

02 / Core application scenarios

Core application scenarios

01
Civil UAVs and electro-optical gimbalsVery-long-range power-line inspection, wide-area GIS surveying, long-range forest-fire sensing, and target coordinate and distance measurement in disaster response.
02
Infrastructure and large-scale engineering monitoringMicro-deformation monitoring of major bridges, dams and high-rise structures, open-pit mine terrain and stockpile surveys, and long-range transmission-tower clearance measurement.
03
Smart security and campus managementPerimeter protection across very large sites, and long-range civil target monitoring at airports, ports and coastlines.
04
Meteorological and ecological researchHigh-altitude meteorological sensing, cloud-base and aerosol height measurement, and undisturbed long-range wildlife observation in reserves.

03 / Core advantages

Core advantages

01
1535 nm eye-safe operationThe 1535 nm band meets Class 1 eye-safety requirements, allowing safe measurement in public spaces and across civil applications.
02
6 km reach with ±1 m accuracyRanges to 6000 m against large structures and natural terrain with accuracy of <±1 m RMS and a selectable 1–10 Hz update rate.
03
Narrow beam for distant targetsA ≤0.3 mrad divergence keeps the spot tight at long range, improving discrimination of small distant targets.
04
Light and efficientA <55 g module drawing ≤3 W average extends endurance on battery-powered platforms, with operation from −40 to +70 °C.
