1570nm RS422 Port Laser Rangefinder Module 20km LRF20E01ES
DESCRIPTION
The LRF20E01ES is a 1570nm eye-safe laser rangefinder powered by diode-pumped OPO technology. This advanced optoelectronic unit achieves refined integration of optical, mechanical and electronic assemblies.
Under standard visibility conditions, it attains an effective ranging range of no less than 20 km for large targets with reflectivity above 20%. When tracking a 2.3m × 2.3m target featuring identical reflectivity, the measurable distance reaches a minimum of 10 km.
It maintains stable ranging precision and is suitable for integration into vehicle-mounted, shipborne and portable optoelectronic observation systems.
