Ultraminiature 905nm Pulsed Laser Ranging Engine

SWaP-Optimized OEM Solution for Weight-Critical Micro-UAV Platforms

The NLMB1000 represents an ultraminiature, high-reliability entry in our series of miniature drone rangefinders, purpose-built for strategic OEM integration in space-constrained systems. Utilizing an ultra-light 905nm sensor architecture, it delivers stable non-contact distance measurement up to 1000 meters with industry-leading SWaP (Size, Weight, and Power) performance.

At a record-breaking weight of ≤10g and a compact Φ17×37.2mm cylindrical form factor, this 10g drone rangefinder supports precision miniature altitude hold and terrain sensing via a standard UART-TTL interface. This unhoused core module architecture allows system architects to achieve seamless mechanical integration into micro-drones, FPV gimbals, and weight-critical aerial platforms.

The system is engineered for mission-critical durability, featuring a narrow blind zone (≤5m), high measurement confidence (≥99%), and stable operation in rugged outdoor environments across a wide temperature range of -20℃ to +60℃ with integrated power reverse polarity protection.
