Hesai JT128 is a 128-channel mechanical lidar whose laser fan spans 95° vertically, from -4.4° below the horizon to 90.5° directly overhead. Rotated through a full 360°, that fan sweeps a cross-section of roughly 189°, which is why the sensor is described as hyper-hemispherical: it removes the blind cone above the unit that a conventional spinning lidar leaves open. It returns 40 m of range at 10% reflectivity on every channel and up to 2,304,000 points per second in dual-return mode, from a sealed IP6K7 housing weighing under 265 g and drawing 8.4 W.
