Simultaneous Color Viewer
GTI’s Simultaneous Color Viewer is designed to detect metamerism and test color harmony by allowing a side-by-side comparison of colors under four different light sources. Standard sources are daylight (D65 or D50), LED, store light (CWF or TL84) and incandescent. A UV light allows for the detection of optical brighteners; it can be used independently or in conjunction with the other sources. A spring-loaded platform allows for thicker materials to be viewed.
