Alpha Prime


With the Alpha Prime, Velodyne Lidar delivers the optimal long-range sensor for autonomous mobility. The Alpha Prime’s world-class combination of range, image clarity and field of view detects roadway objects with reliability and precision.

This state-of-the-art sensor generates high quality perception in a wide variety of light conditions, with advanced sensor-to-sensor interference mitigation, power efficiency, and thermal performance.

Providing long-range detection of low reflectance objects such as tire fragments, dark vehicles, asphalt, and pedestrians, the Alpha Prime enables autonomous operation within a broad range of settings, including urban and highway environments. A culmination of Velodyne’s decade-plus experience engineering and manufacturing lidar, the Alpha Prime is powering safe autonomy.
