LightWare GRF-250 250m
LightWare GRF-250 is an ultra-compact 250 m laser rangefinder designed especially for integration into small EO/IR gimbals and other space-constrained systems.
About This Product
The GRF-250 uses a 905 nm laser and time-of-flight measurement to determine the distance to a target. Its compact 10.7 g body makes it suitable for gimbal payloads where both space and weight are limited. It can provide measurements at up to 50 readings per second and supports detection of multiple targets, making it useful for object ranging, localization and situational-awareness applications.
