The DJI Zenmuse L3 is DJI's long-range, survey-grade aerial LiDAR payload, built exclusively for the DJI Matrice 400. A 1535 nm long-range LiDAR with up to 950 m detection on 10% reflectivity targets (2000 m on 80% targets), dual 100 MP 4/3 CMOS RGB mapping cameras, an integrated POS / IMU, and a 3-axis stabilized gimbal combine into a single 1.6 kg sensor that can cover up to 100 km² per day. The L3 supports up to 2 million points per second, four scan modes (Linear, Star-Shaped, Non-Repetitive), up to 16 returns per pulse, and a 3 cm RGB GSD at 300 m altitude. Paired with a D-RTK 3 Multifunctional Station and DJI Terra, it produces survey-grade point clouds for 1:500, 1:1000, and 1:2000 mapping projects in corridor, area, and powerline-inspection workflows.

DJI's flagship long-range aerial LiDAR for the Matrice 400. 1535 nm laser, 950 m range at 10% reflectivity, 2 MHz pulse rate, dual 100 MP RGB cameras, 3 cm vertical accuracy at 120 m, 100 km² coverage per day.

• DJI SKYPORT mount via the Zenmuse L3 single gimbal connector (sold with the L3 in most configurations)

• Full DJI workflow integration: DJI Pilot 2 (flight planning and data collection), DJI Terra (point cloud processing), DJI Modify (mesh editing), DJI FlightHub 2 (fleet operations)
• PPK differential support for D-RTK 3, D-RTK 2, RINEX 2.1x / 3.0x, RTCM v3.0–3.3 (MSM3–MSM7), and OEM4 / OEM6 base station data
• Class 1 laser safety classification (IEC 60825-1:2014) — eye-safe under normal viewing conditions, no special safety protocols required for ground crews
• IP54 ingress protection; operating temperature -20 °C to +50 °C (-4 °F to +122 °F)

Specifications

Who this is for

• Surveying and mapping firms producing 1:500, 1:1000, and 1:2000 deliverables that need a long-range LiDAR system covering significantly more ground per flight than the L2
• Powerline and transmission inspection operators — the 300 m wire detection range on 21.6 mm conductor, combined with non-repetitive scanning, captures dense corridor geometry from safe stand-off altitudes
• Forestry and biomass crews who need 16-return penetration through dense canopy for bare-earth DEM extraction, stand-density analysis, and timber-volume estimation
• Large-area corridor mapping (highway, rail, pipeline, transmission) — at 300 m AGL the L3 covers up to 10 km² per flight, enabling true 100 km² days with the Matrice 400's extended endurance
• Mining operations producing daily volumetrics, stockpile measurement, and high-wall / facade scans, where the L3's long range allows scanning from positions impossible with shorter-range LiDAR
• Engineering and construction teams generating as-built point clouds for infrastructure and BIM workflows that demand survey-grade vertical accuracy
• Public-safety and federal mapping programs running the Matrice 400 platform that need DJI's most capable enterprise LiDAR sensor as a fleet standard
• Operators upgrading from the Zenmuse L1 or L2 who need significantly longer range, higher pulse rate, dual 100 MP RGB instead of single 20 MP, and the M400 platform's extended payload capacity

What's included

• 1 × DJI Zenmuse L3 LiDAR payload
• 1 × Zenmuse L3 single gimbal connector (required for Matrice 400 mounting)
• Standard accessories — protective lens / case cover and basic documentation as packaged by DJI

Please note: The DJI Matrice 400 aircraft, D-RTK 3 Multifunctional Station, CFexpress Type B memory card, card reader, RC Plus 2 Enhanced controller, and DJI Terra license are sold separately. Specific bundle contents vary by configuration; verify your combo's included accessories at checkout. The L3 is currently supported only on the Matrice 400 — it does not mount to the Matrice 350 RTK, Matrice 300 RTK, Matrice 30 Series, or Matrice 4 Series.

Zenmuse L3 vs. L2 vs. L1

DJI's enterprise LiDAR lineup spans three generations:

• Zenmuse L1: First-generation 905 nm LiDAR with single 20 MP RGB camera, ~450 m detection range at 80% reflectivity, up to 240,000 points per second, three returns. Supports Matrice 300 RTK and Matrice 350 RTK.
• Zenmuse L2: Second-generation 905 nm LiDAR with single 4/3 CMOS RGB camera, ~250 m detection range at 10% reflectivity (450 m at 50%), 240,000 points per second, up to five returns. Supports Matrice 300 RTK, Matrice 350 RTK, and Matrice 400. The mainstream survey LiDAR for mid-range projects.
• Zenmuse L3 (this product): Third-generation 1535 nm long-range LiDAR with dual 100 MP RGB cameras, 950 m detection at 10% reflectivity, 2,000,000 points per second peak, up to 16 returns. Matrice 400 only. The right LiDAR for long-range corridor work, dense canopy penetration, powerline inspection, and survey programs that need maximum coverage per flight.

If your fleet already runs the L2 and you've been hitting range or canopy limits, the L3 + M400 is the upgrade path. If you're starting fresh on a survey program, the L3 is the right choice for any work that benefits from longer range and dual-RGB DOM + DEM capture in a single flight.

D-RTK 3 Multifunctional Station pairing

The L3 produces its best accuracy when paired with a position-calibrated base station. DJI's recommended configuration uses the D-RTK 3 Multifunctional Station as the project base — the L3 stores RTK-fixed positions during flight and supports PPK post-processing in DJI Terra against D-RTK 3 .DAT logs, RINEX files, RTCM streams, or OEM observations from third-party reference networks. Keep the base within 15 km of the aircraft for the rated PPK accuracy. For programs already running D-RTK 2 from earlier M300 RTK / M350 RTK projects, the L3 supports the D-RTK 2 base station as well — the only difference is that the D-RTK 3 also serves as an NTRIP base, network rover, and survey-grade ground point collector in a single unit.
