1570nm Tactical Laser Rangefinder Distance Meter Sensor 20km LRF20C01ES
DESCRIPTION
The LRF20C01ES is a 1570nm tactical laser rangefinder sensor that merges optical, mechanical and electronic subsystems into one integrated unit.
Under standard visibility, it delivers effective ranging performance: minimum 20 km detection range for large targets with reflectivity ≥20%, and at least 10 km for a 2.3m × 2.3m target with identical reflectivity.
Boasting compact dimensions, lightweight build, outstanding reliability and extended service life, the module supports high-accuracy distance detection for remote targets.
It can be flexibly embedded into portable observation equipment, vehicle-borne and airborne optoelectronic platforms.
