Abstract: This paper presents the results of refractive-index measurements of the extraordinary and ordinary rays in nematic liquid crystals (NLCs) using a refractometric technique in the mid-IR (gimel = 10.6 mu m) and near-IR (gimel = 1550 nm) regions for NLC E7 and at (gimel = 1550 nm) regions for NLC K15. The optical anisotropy of NLC E7 at 10.6 mu m is determined independently by means of the interferometric method in order to compare it with the results obtained by the refractometric technique.
