Color Analysis

Color analysis in machine vision uses the spectral properties of illumination and camera sensors to classify, sort, and verify products based on colour. Accurate colour inspection requires LED illuminators with stable, reproducible spectral output and high Colour Rendering Index (CRI) to distinguish subtle colour differences between products, detect print defects, verify label colours, and sort items by hue. RGB LED illuminators allow engineers to select or combine red, green, and blue channels to maximise contrast for specific colour-based inspection tasks without changing hardware. RODER Vision LED illuminators for colour analysis deliver consistent colour temperature and spectral stability over time, ensuring repeatable results across production shifts. Applications include food colour sorting, paint finish verification, pharmaceutical tablet inspection, label print quality control, and colour coding verification in electronics and packaging manufacturing.
