Abstract

Absorption and scattering losses of visible radiation in nematic liquid crystals (LCs) were measured by an improved transmission technique. The absorption loss of the E-7 LC mixture was found to be ~1 order of magnitude larger than the scattering in the isotropic state. On the contrary, light scattering surpasses absorption by ~2 orders in the nematic state. Wavelength-dependent absorption and scattering losses of two LCs, E-7 and MBBA, were investigated at some laser wavelengths. Results indicate that the absorption tail of LCs decreases with wavelength as λ−2 and scattering as λ−4 as expected by theory.
