Hesai AT128 Automotive-Grade 120-Degree Long-Range LiDAR
128-line automotive LiDAR with 210 m range and 1,536,000 points per second
Overview
The Hesai AT128 is an automotive-grade hybrid solid-state LiDAR with a 120-degree horizontal field of view and a true 128-line vertical scan. It measures 210 m at 10% reflectivity, outputs 1,536,000 points per second (single return) and provides a global resolution of 1200 x 128 with angular resolution of 0.1 degrees horizontal and 0.2 degrees vertical. The unit consumes 13.5 W and weighs 940 g, making it suitable for ADAS, autonomous driving and industrial mobile platforms.
