Frequently Asked Questions ▾
What is the Orbbec Pulsar SL450? ▾
The Pulsar SL450 is a cost-effective single-line LiDAR for robotic navigation. It uses direct Time of Flight (dToF) ranging and is built around a high-precision rotating-mirror optical scanning system with a high-frequency laser pulse transmitter. Its optical, mechanical, and structural design allows robust, accurate scanning across a 270 degree horizontal area up to a distance of 45m, suiting it to robot positioning and navigation, area security, logistics, environmental scanning, and 3D scene reconstruction.
What is the measurement range and accuracy of the Pulsar SL450? ▾
The Pulsar SL450 has a measurement range of 45.0m at 90% reflectivity and 15.0m at 10% reflectivity. Its accuracy is plus or minus 20mm at 90% and plus or minus 25mm at 10%, with a precision of 15mm or better at both 90% and 10% reflectivity. It uses a 903nm laser and can operate in ambient light up to 60,000 Lux.
How detailed is the Pulsar SL450's point cloud? ▾
The Pulsar SL450 supports high-density point cloud scanning with a measurement frequency of up to 72 kHz and an angular resolution as fine as 0.075 degrees. Selectable angular resolutions include 0.075, 0.1, 0.125, 0.15, and 0.2 degrees, so you can balance detail against data rate. It scans a 270 degree horizontal area, helping capture fine surface detail without missing features.
How does the Pulsar SL450 perform in dust or fog? ▾
The Pulsar SL450 combines reliable ranging with a multi-echo noise filtering design, which enables precise scanning and accurate data feedback even in environments containing light dust or fog. It also delivers a high degree of point cloud consistency, with uniform accuracy and precision that avoids varying positive or negative offsets, so each sensor produces maps of consistent quality.
Is the Pulsar SL450 suitable for demanding environments? ▾
Yes. The Pulsar SL450 carries an IP65 ingress protection rating and uses a Class 1 laser that is safe for the eyes. It operates across an ambient temperature range of -10 to 55 degrees Celsius. It measures 60mm x 60mm x 88mm and weighs about 320g, making it compact enough for mobile robot integration.
What are the typical applications for the Pulsar SL450? ▾
The Pulsar SL450 is used for warehouse AMRs, autonomous forklifts, and commercial service robots. Its 270 degree scanning angle, long range, and consistent mapping make it well suited to robot positioning and navigation as well as environmental scanning.
