A system, method and composition for coloring dental ceramics. According to the invention, the lens consists of a substrate that consists of a ceramic having a predetermined shape and at least another material, which covers a surface of the substrate at least in certain sections in order to form a lens surface. The method further comprises calculating a first average power based on data transmitted during the first measurement, calculating a second average power based on data transmitted during the second measurement, and compensating at least one of the first measurement and second measurement based on a difference between the first average power and the second average power. In still another aspect, an article of commerce communicates to the consumer that the product comprising cocoa beans has reduced or low levels of asparagine andor acrylamide. A computer can be used to translate displacement data into a 3D mapping representative of the 3D object being encoded.
