The Intel RealSense L515 is the world's smallest high-resolution Solid-State LiDAR depth camera, purpose-built for precision indoor 3D scanning and measurement tasks. Unlike active -stereo depth cameras, the L515 uses a proprietary MEMS micro-mirror scanning system to sweep an infrared laser across the scene — delivering true laser-ranging depth accuracy of ≤5 mm at 1 m and maintaining sub-centimetre precision across its entire 0.25 m – 9 m operational range. This makes it dramatically more accurate than any RealSense stereo camera at mid-to-long range, especially on featureless or low-reflectivity surfaces where stereo algorithms struggle. The L515 outputs a high-density depth map at up to 1024 × 768 @ 30 fps — 23 megapixels of depth per second — with exceptional edge fidelity that keeps object boundaries sharp and free from the smearing common with stereo systems. A co-registered 1920 × 1080 RGB camera (rolling shutter, 70° × 43° FOV) provides full HD colour overlay. The cylindrical body measures just Ø61 mm × 26 mm and weighs only 100 g, making it the most compact high-precision LiDAR camera in the RealSense lineup. A built-in RealSense Vision ASIC handles all depth computation on-device, keeping the host CPU free and enabling full bus-powered operation over a single USB-C 3.1 Gen 1 cable at under 3.5 W. Multi-camera deployments are fully supported via hardware synchronisation, enabling volumetric capture, 360° scanning rigs, and industrial inspection stations. The open-source Intel RealSense SDK 2.0 (librealsense) provides Python, C++, C#, ROS, and Unity/Unreal plugins — the same SDK used across the entire RealSense family. Whether you need centimetre-accurate volume measurement for logistics, high-fidelity 3D scans for reverse engineering, or precise bin-picking data for warehouse robotics, the L515's LiDAR-grade accuracy in a USB-powered, palm-sized form factor is in a class of its own. Features Solid-State LiDAR Depth Technology — proprietary MEMS micro-mirror scanning with an IR laser; delivers laser-ranging accuracy (≤5 mm at 1 m) that far exceeds stereo depth cameras at mid-to-long range and on low-reflectivity surfaces Long & Precise Depth Range — 0.25 m – 9 m operational range; ≤5 mm average error at 1 m, ≤14 mm at 9 m (95% reflectivity); consistent sub-centimetre accuracy across the full range High-Density Depth Output — up to 1024 × 768 @ 30 fps, producing 23 megapixels of depth per second; dense point clouds with sharp edges and no smearing True Laser Ranging — uses 860 nm NIR laser (Class 1 eye-safe) instead of passive stereo; works reliably on featureless walls, floors, and low-contrast surfaces that defeat stereo algorithms Compact Cylindrical Form Factor — Ø61 mm × 26 mm, 100 g; world's smallest high-resolution LiDAR depth camera; easily mounts on robots, handheld scanners, and space-constrained installations Full HD RGB Overlay — 1920 × 1080 @ 30 fps RGB camera (rolling shutter) with 70° × 43° FOV; co-registered with depth for accurate colour-point-cloud generation USB-C Bus-Powered — entire depth + RGB pipeline draws Show more
