PRODUCT DESCRIPTON
ERDI LASER® LRF1830C is an 18 km laser rangefinder using a 1535 nm erbium-glass laser with ±2 m accuracy. It supports single-pulse TOF measurement, multi-target detection (up to 3 targets), and includes RS422 interface, embedded software, and self-diagnostics.
Designed for UAVs, photoelectric targeting, and unmanned platforms, it operates reliably in harsh environments (−40°C to +65°C) and meets Class 1 eye safety standards.
Key Advantages
-
Ultra-Long Range: ≥18 km detection on 4×6 m targets with ±2 m accuracy.
-
Multi-Target & Intelligent Functions: Up to 3 targets, distance filtering, and self-diagnostics.
-
Integration-Ready: RS422 interface and embedded software for easy system adaptation.
-
Rugged & Reliable: MIL-STD-810G certified for shock, vibration, and extreme temperatures.
