Reference Tiles uv which is considered the highest

which is considered the highest grade reference material for diffuse reflectance

For low absorption measurements and flow cell cuvettes

but the collimating lenses are placed under an angle of 90 degrees from one another

Collimating lenses can be used in any optical setup that require parallel beams of light at the illumination source and/or at the entrance optics

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
