Reference Tiles uv but the collimating lenses are

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

a variable pathlength cuvette holder is an ideal solution

reflection probes are used

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

and a cover to prevent ambient light from entering the light path

Reference Tiles uv but the collimating lenses areFor 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
