For diffuse reflection measurements, Avantes offers the WS-2 reference tile, while the RS-2 is ideal for specular reflection measurements.
The WS-2 reference tile is made from a high-quality white diffuse PTFE-based material, which is considered the best reference material for diffuse reflectance. It is primarily used in colorimetric applications, where obtaining a reference signal during a reflection measurement is crucial. The RS-2 is a mirror tile designed to serve as a reference standard for specular reflection measurements, ensuring accurate and consistent results for such applications.
