LightWare GRF-500 500m
LightWare GRF-500 is a compact 500 m laser rangefinder designed for integration with EO/IR gimbals and other systems where long-range distance measurement is required without adding significant weight.
About This Product
The GRF-500 uses a 905 nm laser to measure target distance using time-of-flight technology. Its compact 10.7 g form factor makes it suitable for space- and weight-constrained gimbal systems. It can measure distances up to 500 m under the manufacturer’s specified test conditions and provides configurable measurement rates from 0.5 to 10 readings per second.
