PRODUCT DESCRIPTON
Key Advantages
- Long-range performance: Eye-safe 1535nm TOF laser delivers up to ≥4000m ranging on NATO targets.
- High reliability: MIL-STD-810G shock & vibration resistance, stable operation from −40℃ to +70℃.
- High accuracy: ±2m measurement accuracy, ≥98% precision, ≤1% false-alarm rate.
- Advanced detection: Supports multi-target detection (up to 3 targets) and first/last/continuous ranging modes.
