905nm LiDAR Reflectance Target: Selection and Testing Guide
905nm is the dominant wavelength for short-to-medium-range LiDAR systems in 2026 — used by Hesai, Velodyne, RoboSense, Innoviz, Roborock, and most current-generation automotive forward-sensing LiDAR. This guide covers why 905nm dominates, who uses it, recommended target sizes and reflectance values for 905nm testing, and the common pitfalls that invalidate test results at this wavelength.
