Reference Tiles uv and a cover to preventFor diffuse reflection measurements, the WS 2 reference tile is ideal. For specular reflection measurements, the RS 2 is available. The WS 2 reference tile is made out of a white diffuse PTFE based material, which is considered the highest grade reference material for diffuse reflectance. It is mostly used in colourimetric applications where a reference signal has to be obtained during a reflection measurement. The PTFE material is high purity and
