Frequently Asked Questions ▾
What is the Orbbec Pulsar ME450? ▾
The Pulsar ME450 is a cost-effective 3D LiDAR that supports multiple scanning patterns. It is based on direct Time of Flight (dToF) ranging and uses a high-performance optical system that combines MEMS-based pitch scanning with motorized azimuth control, emitting 200 kHz laser pulses. It offers a maximum detection range of up to 45 meters at 90% reflectivity, making it suitable for both robot navigation and obstacle avoidance and for general-purpose laser scanning for surveying.
What scanning patterns does the Pulsar ME450 support? ▾
The Pulsar ME450 offers configurable multi-pattern scanning, allowing you to switch patterns without changing devices. It supports non-repetitive scanning and repetitive scanning at several densities, including non-dense, 2x dense, and 4x dense modes. A single unit can meet a range of 3D data acquisition requirements.
How accurate is the Pulsar ME450? ▾
The Pulsar ME450 achieves millimeter-level accuracy and precise localization for high-fidelity 3D reconstruction, with reliable reflectivity detection and stable performance across complex materials and interference. Millimeter-level accuracy applies under typical indoor conditions, for example white walls within 30m or 10% reflectivity targets within 10m; in outdoor or long-range cases, error may exceed 10mm.
Is the Pulsar ME450 suitable for harsh environments? ▾
Yes. The Pulsar ME450 is engineered to withstand vibration and shock and carries an IP67 dust and waterproof rating. It also provides ambient light immunity and crosstalk immunity in multi-device opposed-beam systems, which supports reliable operation where several units face one another or where strong ambient light is present.
What are the typical applications for the Pulsar ME450? ▾
The Pulsar ME450 is used across mobile robotics and industrial applications, including lawn mowers, forklifts, warehouse AMRs, and logistics vehicles. Its configurable scanning patterns let a single sensor serve both navigation and obstacle avoidance as well as surveying-style laser scanning.
What software supports the Pulsar ME450? ▾
The Pulsar ME450 is supported across the full Orbbec SDK suite. Orbbec Viewer provides LiDAR-focused preview and configuration, sharing the same SDK and tools used with Orbbec depth cameras across platforms, which simplifies development for teams already using Orbbec products.
How does the Pulsar ME450 differ from the Pulsar SL450? ▾
The Pulsar ME450 is a multi-pattern 3D LiDAR that combines MEMS pitch scanning with motorized azimuth control and offers configurable repetitive and non-repetitive scanning with an IP67 rating. The Pulsar SL450 is a single-line LiDAR built around a rotating-mirror optical system with a 270 degree horizontal scanning angle and an IP65 rating. Both use dToF ranging and reach up to 45m, but they target different scanning needs.

The Orbbec Pulsar ME450 is a compact, cost-effective 3D dToF LiDAR that redefines robotic perception through configurable multi-pattern scanning. Unlike single-line sensors such as the Pulsar SL450, the ME450 features a broad 270° horizontal and 60° vertical field of view—with vertical FOV software-configurable to 45° or 30°—allowing operators to adapt scan patterns to both close-range obstacle avoidance and wide-area surveying from a single device.

Powered by direct Time-of-Flight (dToF) technology at 905 nm, the Pulsar ME450 emits 200 kHz laser pulses to deliver precise point clouds up to 45 m at 90% reflectivity (and 15 m at 10% reflectivity) with ±30 mm accuracy and ≤20 mm precision. An integrated 6-axis IMU combined with PTP, GPS, and PPS time-synchronization fuses vehicle motion and spatial data with high fidelity, while 80,000 Lux ambient light tolerance ensures stable operation under intense sunlight or reflective industrial lighting.

Engineered for autonomous mobile robots (AMRs), automated guided vehicles (AGVs), perimeter security, logistics sorting, and 3D scene reconstruction, the ME450 features a rugged IP67 enclosure, low power consumption (<6W, 9–28V DC input), and a weight of just ~270 g. It connects via an M12 8-pin aviation connector (100 Mbps network) and integrates seamlessly with Windows and Linux setups using the open-source Orbbec SDK. Certified with Class 1 laser safety and operating from -20 °C to 55 °C, the Pulsar ME450 offers premium 3D perception at an accessible $549 price point—order today, or explore the Pulsar SL450 for 2D single-line navigation needs.
