Meet the LIDAR-Lite v3: an optical distance measurement system from Garmin that lets you experiment with your drone, robot, and unmanned vehicles. This 40-meter range sensor is lightweight and small. It also doesn’t consume a whole lot of power.
The LIDAR-Lite v3 comes with a 905nm single-stripe laser transmitter, 4 m Radian x 2 m Radian beam divergence, and an optical aperture of 12.5mm. You can adjust its operating range and measurement time.
