Multispectral Vision

Multispectral vision systems capture images at multiple specific wavelengths simultaneously or in rapid sequence, enabling inspection tasks that are impossible with single-wavelength or white light illumination. By comparing how a material reflects or absorbs light at different wavelengths, multispectral machine vision can detect hidden defects, verify chemical composition, distinguish between visually similar materials, and identify contamination invisible to RGB cameras. Multispectral LED illuminators provide controlled, repeatable output at defined wavelengths from UV through visible to near-infrared and SWIR. RODER Vision multispectral illumination solutions support agricultural sorting, pharmaceutical ingredient verification, food safety inspection, recycling and material classification, and advanced surface analysis applications. Programmable multi-wavelength LED systems allow engineers to optimise spectral configuration for each inspection task without hardware changes, enabling flexible multispectral imaging on multi-product production lines.
