LightwareLightWare GRF-500 (500m) Laser Rangefinder

LightWare LiDAR GRF-500 Laser Rangefinder is a compact, ultralight 500m/1640ft laser rangefinder optimized for low power consumption and easy integration with EO/IR gimbals and ranging measuring systems. The LightWare LiDAR GRF-500 utilizes the time-of-flight principle to measure distance to objects. The system emits a rapid succession of laser pulses that reflect off the targeted object until the receiver reaches the designated lasing time. GRF-500 utilizes 905nm laser technology, ensuring optimized performance while meeting class 1M eye safety standards.
