PRODUCT DESCRIPTON

The ERDI LASER® LRF0818C 8km Laser Rangefinder Module is a compact, high-precision 1535 nm eye-safe TOF laser rangefinder designed for professional long-range measurement applications. With a maximum range of up to 8 km, it supports first/last target detection, range gating, and built-in self-test (BIST), enabling stable and reliable performance across UAVs, robotics, and tactical or industrial systems.

Key Advantages

• Ultra-long-range capability: Up to 8 km detection on 2.3×4.6 m vehicle targets with ±2 m accuracy.
• Rugged and field-proven: MIL-STD-810G qualified for vibration, shock, and extreme temperature environments.
• Enhanced measurement functions: First/last target detection, range gating, and BIST for high-reliability operation.
• Compact & low-power design: Lightweight (≤65 g), small form factor (≤59.5×26×32 mm), and low standby consumption (≤1 mW).
