Hesai launches MT series lidar for high-precision 3D mapping, claiming smallest form factor in its class
Hesai Technology unveiled its MT series lidar at INTERGEO 2026 in Germany, promising ultra-high spatial resolution and 3.5 mm ranging precision in what it calls the smallest form factor in its class.

What Happened
Hesai Technology unveiled its MT series lidar at INTERGEO 2026 in Germany, describing it as its next-generation flagship lidar series with ultra-high spatial resolution for high-precision 3D reconstruction. The series packs three key innovations into the smallest form factor in its class: an ultra-small beam spot, ultra-high ranging precision of 3.5 mm, and cumulative scan densification, which Hesai says together deliver exceptional spatial resolution and finer, denser 3D data. INTERGEO is a key showcase for the latest technologies and emerging trends in high-precision 3D modeling, and Hesai says the MT drew significant industry attention on its official debut. The product has already been integrated into NavVis VLX 4, the latest wearable capture device from reality-capture company NavVis.
- An ultra-small beam spot that captures fine structures, complex edges and narrow spaces with greater precision.
- Ultra-high ranging precision of 3.5 mm for highly accurate spatial geometry.
- Cumulative scan densification, which continuously builds denser, more complete point clouds.
- 70% smaller than the XT
- 3.5 mm, a 30% improvement over the XT
- 40% reductions in both versus the XT
over 70%
Based on on-site statistics from INTERGEO 2026, ranking Hesai No. 1 globally in the high-precision 3D modeling lidar market.
High-precision 3D mapping often involves long, continuous hours of fieldwork, so the MT series weighs just 300 g with a diameter of 6.4 cm and is over 40% lighter than the previous generation. Hesai says the lightweight design reduces fatigue during extended handheld operation and makes on-site data capture easier and more flexible. The sensor also offers a field of view of up to 320° × 60°, with 1.5 times the vertical FOV coverage of the previous generation, so a single scan captures a larger area and users need to move the device less. Hesai says this combination of portability and performance makes high-precision 3D data capture easier and more efficient.
In challenging environments such as dense forests and industrial facilities, overlapping foliage, intertwined pipelines and narrow gaps can cause occlusion and mixed returns, resulting in missing point cloud data and repeated scans. Hesai says the MT's ultra-small beam spot improves gap detection, capturing more data through gaps in dense foliage to reveal terrain beneath the canopy and multi-layer vegetation, and capturing pipes, cables and equipment through narrow spaces with less occlusion. The MT series is integrated into the NavVis VLX 4, described as the first NavVis capture device to deliver true 3 mm point cloud resolution in dynamic scanning, an integration that builds on collaboration between the two companies during MT development and supports high-detail Scan-to-BIM, MEP and industrial workflows. To date, Hesai says it has supplied its high-precision lidar solutions to more than 270 customers across over 20 countries.
Previously from Hesai Technology
Earlier MotorClaw coverage shows Hesai's lidar appearing outside vehicles: a team of ETH Zurich students built a self-riding bicycle prototype around a Hesai JT128 lidar and showed it could ride itself across campus and park. We have also reported that 3D lidar, long tied to autonomous driving, is finding new value in slow-speed precision docking, from aircraft gates to robot chargers. Hesai was also named to Morgan Stanley's Humanoid 100, with the bank citing its robotic actuation modules and lidar.

Why this matters
The MT series targets surveying, mapping and digital-twin work, where tighter ranging precision and denser point clouds reduce the need for post-processing calibration and repeated scans. Buyers in the AEC and mobile-mapping industries get a 300 g device that Hesai says is easier to carry through long fieldwork, and NavVis VLX 4 users are the first to have it integrated.
