Color comparator system

摘要

A color comparator system is described which avoids the use of liquid reference standards and glass vials. In a preferred embodiment the system includes (a) a clear lens piece including a plurality of lens sections equal to the desired number of color steps or intensities to be measured or observed; (b) background color for visually separating the lens sections and providing a controlled background color for samples between lens sections; and (c) at least one lens color means positioned behind the lens piece. The visual perception when using this comparator system is the same as viewing a series of glass tubes filled with colored liquid. Ambient light passes through each lens and is then reflected back toward the viewer.
