Drone Laser Rangefinder Modules for UAV Payloads
1535nm Airborne Ranging Series
SWaP-Optimized Erbium Glass Cores for High-Altitude UAV Payloads
ntron's airborne series is meticulously engineered to address the critical SWaP (Size, Weight, and Power) requirements of modern unmanned systems. Utilizing proprietary Diode-Pumped Solid-State (DPSS) technology, these 1535nm Erbium Glass modules provide the high beam quality necessary for Drone Gimbals, UAV Altitude Hold, and Precision Photogrammetry. By minimizing power consumption (down to ≤1.0W), our sensors help maximize drone flight endurance while delivering mission-critical distance data from ranges up to 20km.
Designed to excel in harsh field environments and high-altitude aerospace payloads, this series features exceptional vibration resistance and thermal stability across a -40°C to +70°C range. The inherent 1535nm wavelength ensures superior atmospheric penetration through fog, haze, and smoke, providing reliable target acquisition for search-and-rescue, tactical mapping, and night operations. With NVG-invisible stealth and Class 1 Eye-Safety, these modules are the definitive core for professional UAV integration.
