PRODUCT DESCRIPTON
ERDI LASER® LRF1829C Laser Rangefinder Module is a compact 1535nm Class 1 eye-safe TOF laser rangefinder delivering measurement distances up to 23 km with ±2 m accuracy. Featuring multi-target detection, ultra-low power consumption, MIL-STD-810G durability, and easy integration, it is ideal for UAV payloads, EO/IR systems, surveillance, border security, and defense platforms.
Key Advantages
Up to 23 km Measuring Range: Measures vehicle targets up to 18 km and diffuse reflective targets up to 23 km under favorable conditions.1535nm Class 1 Eye-Safe Laser: Eye-safe erbium glass laser technology enables reliable long-distance ranging.
High Precision Performance: Provides ±2 m accuracy, ≤0.1 m resolution, and ≥98% ranging precision.
Multi-Target Capability: Simultaneously detects and reports distances to up to 3 targets.
Energy-Efficient Operation: Average power consumption of ≤2 W, suitable for UAV and portable electro-optical systems.
Compact & Lightweight Design: Dimensions of 125 × 100 × 72 mm and weight ≤400 g simplify integration into space-constrained platforms.
Military-Grade Ruggedness: Complies with MIL-STD-810G requirements for shock and vibration resistance.
Wide Environmental Adaptability: Operates reliably from −40°C to +70°C for demanding outdoor and defense applications.
