Reference Tiles uv but the collimating lenses are

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

reflection probes are used

The special WS-2-GEM is designed to facilitate holding and cooling a gemstone with liquid nitrogen

The other two ports on this version have SiO2 coated aluminum mirrors which reflect otherwise lost emissions back into the collection lens which serves to enhance the excitation and fluorescence signals

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
