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.
How to Evaluate Checkerboard Calibration Target Accuracy: 4 Numbers That Matter
If you buy calibration targets, your supplier’s inspection report is the only thing that lets you trust a part you can’t easily measure yourself. But most reports give you raw deviation numbers that conflate two unrelated things — how accurately the part was actually made, and how the operator placed it on the measurement stage. […]
Autonomous Vehicle LiDAR Testing — Complete Reflectance Target Guide (2026)
Autonomous vehicle LiDAR testing follows a structured progression from research validation through OEM acceptance to production qualification, with reflectance target requirements that escalate at each stage. This guide covers SAE Level requirements, ISO 21448 SOTIF and ISO 26262 functional safety frameworks, multi-reflectance test protocols, and what separates a defensible AV LiDAR test program from one that fails OEM scrutiny.
LiDAR Detection Range vs Reflectance — Complete Physics Guide (2026)
LiDAR detection range scales with the square root of target reflectance — a 90% target detects at roughly 3× the range of a 10% target. This guide explains the LiDAR range equation, why datasheet “maximum range” claims need careful interpretation, and how to use reflectance test data to predict real-world detection performance against any scene.
1550nm LiDAR Reflectance Target — Long-Range Automotive Testing Guide (2026)
1550nm is the wavelength of choice for long-range automotive LiDAR — used by Luminar, Aeva, Aurora, Innoviz Pro, and Hesai AT-class systems for detection beyond 250m. This guide covers why 1550nm dominates long-range LiDAR, who’s using it, recommended target sizing for 200-400m testing, and the SWIR-specific calibration considerations that make 1550nm test setups different from 905nm.
Custom LiDAR Reflectance Targets — When Standard Sizes Aren’t Enough (2026)
Custom LiDAR reflectance targets cover applications where standard sizes, reflectance values, or wavelengths don’t fit your test program. This guide explains when custom is the right call, what’s manufacturable (sizes up to 3m × 5m, reflectance from 1% to 99%, custom mounting and weatherproof options), and how to spec a custom order to get usable results on the first delivery.
Lambertian vs Specular vs Retroreflective Targets — Which Do You Need? (2026)
Three fundamentally different reflection modes — Lambertian (diffuse), specular (mirror), and retroreflective (back-toward-source) — define optical and LiDAR test targets. Lambertian is the standard for reproducible measurement. This guide explains the physics behind each, when to use them, and how to verify your target actually behaves the way it should.
How to Test LiDAR Performance with Reflectance Targets (2026 Lab Setup Guide)
A complete LiDAR performance test characterizes detection range, range accuracy, and intensity calibration using calibrated reflectance targets in a controlled lab environment. This step-by-step guide walks through equipment requirements, environmental controls, the three core test protocols, common mistakes that invalidate results, and the documentation needed for OEM-defensible test reports.
