PRODUCT DESCRIPTON
ERDI LASER® LRF1830C Laser Rangefinder Module is a compact 1535nm Class 1 eye-safe TOF laser rangefinder offering up to 23 km long-range measurement with ±2 m accuracy. Featuring low power consumption, multi-target detection, rugged MIL-STD-810G compliance, and UART/RS422 compatibility, it is ideal for UAVs, EO/IR systems, surveillance, and defense applications.
Key Advantages
- Ultra Long Measuring Range: Measures up to 23 km against 30% reflective diffuse targets and 18 km for vehicle targets.
- 1535nm Class 1 Eye-Safe Laser: Uses an eye-safe 1.54 μm erbium laser suitable for long-range outdoor applications.
- High Measurement Accuracy: Delivers ±2 m ranging accuracy with 0.1 m resolution and over 98% precision.
- Multi-Target Detection: Detects and returns distances for up to 3 targets simultaneously.
- Low Power Design: Average power consumption of only ≤2 W, ideal for battery-powered UAV and portable systems.
- Compact & Lightweight: Measures 125 × 100 × 70 mm and weighs ≤400 g for easy system integration.
- Rugged Military-Grade Reliability: Meets MIL-STD-810G standards for shock and vibration resistance, ensuring reliable operation in harsh environments.
- Wide Operating Temperature: Stable performance from −40°C to +70°C, suitable for demanding field conditions.
