Dataset description

The data included was used to analyse the performance of pure and dye doped liquid crystal Fresnel lens. The data is referenced in “Efficiency improvements in a dichroic dye-doped liquid crystal Fresnel lens" by E. I. L. Jull, Markus Wahle, Peter J. M. Wyatt, Collin Ellis, Kiyoaki Usami, and H. F. Gleeson. Different modelling and experimental procedures were used in obtaining the data included, further detail of which can be found in the data descriptions.
