Wedge-cell technique as a simple and effective method for chromatic dispersion determination of liquid crystals
Katarzyna Rutkowska , Kamil Orzechowski , Marek Sierakowski
AbstractIn this letter we present a wedge-cell method and then compare it with other techniques that can be used to determinate refractive indices of liquid crystalline materials. This simple goniometric technique is of particular significance when used for liquid crystalline materials characterized by high refractive indices, for which refractometric methods are approaching their upper limits. Importantly, a measurement technique proposed here requires relatively small amount of a liquid crystalline material and gives appropriate results for different light sources from the wide spectral range, allowing thus for chromatic dispersion curves (in different temperatures) to be obtained. © 2016 Photonics Society of Poland.
