About This Product

The SF30/D uses laser time-of-flight measurement to determine the distance to a target. It can deliver up to 20,000 readings per second, allowing the sensor to respond quickly to changes in the surrounding environment. Its first- and last-pulse processing provides additional return information, making it useful for applications such as above-ground-level measurement, terrain following and obstacle detection. LightWare also highlights its performance when measuring low-reflectivity surfaces and height above water.
