An enhanced optical micro-fading device

This paper introduces a new set-up for the determination of colour change on cultural heritage objects, referred to herein as stereo-microfading tester. The system uses high quality optics through implementation stereo-microscope its central element. technology enables developments such incorporation imaging systems, and separation fading measurement processes. describes this micro-fading evaluates performance against traditional devices based blue wool standards. results show correlation between obtained different while highlighting significant variability inherent samples
