Overview
The Lumispot ELRF-H25 is a professional laser ranging module built on a self-designed 1535 nm erbium laser. It uses a single-pulse time-of-flight (TOF) method to achieve a maximum measurement range of ≥8 km. The module integrates the laser, transmission optics, receiving optics, and a control circuit board in a compact, lightweight form factor. It is Class 1 eye-safe and designed for stable performance and high impact resistance.
