PRODUCT DESCRIPTON
The ERDI LASER® LRF0105C is a high-performance 3km Laser Rangefinder using erbium glass laser with proprietary bonded crystal technology. Class 1 eye-safe, it measures up to ≥3000m for NATO targets and ≥1500m for human targets. Compact (Φ34×47.5mm) and lightweight (≤29g), it supports 1–10Hz ranging frequency, multi-target detection, and low power consumption, ideal for UAV pods, border surveillance, and handheld systems.
Key Advantages
-
Ultra-compact and lightweight, easy integration into UAVs and portable systems.
-
High-precision long-range performance with ±2m accuracy and ≤1% false alarms.
-
Robust and reliable, shock- and vibration-resistant, operating from -40℃ to +70℃.
-
Flexible operation, supporting single-shot, multi-target, and adjustable 1–10Hz ranging.
