What is a Translucent Sample
Translucence: Samples which exhibit a certain amount of scattering and are not totally transparent or totally opaque. When light strikes a translucent object, some of the energy is absorbed, and some of the light is diffused. Some of the light which is diffused, or scattered, ultimatley passes through the colored sample. The result is that the background can be seen, but is not clearly identifiable. In industrial applications, it is important to identify if a sample is transparent, translucent or opaque. For a translucent sample, the degree of translucency can be identified through a contrast ratio calculation. This calculation requires that the sample be presented over a white background as the Standard, and again over a black background as the Trial. The contrast ratio calculation can be found among the Indices selections.
