Laser Range Finder 905nm

Wavelength & Eye Safety: The 905 nm wavelength is in the near‑IR band and many modules operate in Class 1 laser safety mode at this wavelength.

Range Capability: Some modules claim ranges up to ~1.0 km to ~4.0 km or more under ideal conditions (large reflector targets, clear visibility).

Compact / Low Power: Modules are designed for integration (drones, UAVs, portable devices) at low weight (some under ~50 g) and modest power consumption.

Interfaces & Integration: Typical modules provide TTL/RS232 output or similar digital interface, allowing integration into systems (data logging, targeting, C2).

Accuracy & Resolution: Accuracy in typical good conditions may be ±1 m for shorter ranges; resolution may be ~0.1 m with proper target/conditions.

Application Suitability: Good for surveying, UAV altitude/obstacle sensing, security/perimeter measuring, and other non‑military “targeting” use. Note: for covert/tactical LRFs, other wavelengths or features (eye‑invisibility, anti‑detection) may be preferred
