OS-2 Long-Range High-Resolution Imaging Lidar

The OS-2 is a high-performance long-range imaging lidar designed for advanced autonomous systems and demanding industrial environments. Delivering exceptional range, high angular resolution, and robust all-weather reliability, the OS-2 enables superior object detection and situational awareness for long-distance perception applications.

With up to 200 m range on a 10% reflectivity target and over 400 m maximum range, the OS-2 combines extended detection distance with precise 3D point cloud generation. Powered by Ouster’s advanced L3 chip architecture, it provides enhanced range performance while maintaining compact, ruggedized hardware rated for IP68/IP69K environments.
