Reference Tiles uv which is considered the highest

which is considered the highest grade reference material for diffuse reflectance

The light from a light source is sent through six illumination fibres to the sample and the reflection is measured by a 7th fibre that's mounted in the centre of the reflection probe tip

reflection probes are used

Versions with a greater number of fibres are available if extra energy is required to increase the reflectance signal

Reference Tiles uv which is considered the highestFor 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
