The WS-2 white reference tile is made out of a white diffuse PTFE based material, meeting the highest demands with regard to high grade diffuse reflectance. The WS-2 is mostly used in colorimetric applications where a reference signal has to be obtained during a reflection measurement.
Thanks to most accurate preparation of the PTFE and its processing to an amorphous structure, the tile reflects light from 350-1800 nm with ca 98% and from 250-2500 nm more than 92%. The material offers long term stability, even in UV applications. The plastic is hydrophobic and chemically inert.
Specially for gemmology applications the WS-2 is used in combination with a reflection integrating sphere. The gemstone is then put on the middle of the tile, the integrating sphere over it. A special WS-2 tile (WS-2-GEM) was developed to be able to cool the gemstones with liquid nitrate, therefore a hole was designed in the middle of the tile.
The material can be delivered as custom designed items, contact us for more information.
