1570nm OPO Laser Rangefinder Module 20km LRF40H20
DESCRIPTION
LRF40H20 is a 1570nm eye-safe OPO laser rangefinder module based on diode-pumped optical parametric oscillation technology. Integrated with precision optical, mechanical and electronic components, this rangefinder supports ultra-long-distance ranging up to 40 km.
With stable ranging precision, compact structure and robust environmental adaptability, the unit adopts standard RS422 communication interface for easy integration. Widely applied in airborne electro-optical pods, terrain survey, border monitoring, search & rescue and long-range observation systems.
