Hardware Complex for Studying the Electro-Optical Parameters of Mesogens
I.S. CHEKULAEV, A.D. KURILOV, G.T. CHANTURIYA, T.A. BULANOVA, V.A. BULANOV, V.A. ZHACHKIN, D.N. CHAUSOV

A hardware complex has been developed for studying the electro-optical parameters of mesogens in a wide range of temperatures
(–40–160 °C) and wavelengths (360–900 nm), opening up the opportunity to study new mesogens and determine the temperature behavior
of the dispersion of refractive index anisotropy. The proposed approach makes it possible to reduce the random error in determining electrooptical parameters due to statistical processing and minimization of the temperature fi eld gradient. The developed complex was tested on the
well-known nematic mixture ZhK-1289, the obtained values coincide with the literature data. The random error in determining electro-optical
parameters has been reduced by 4 times.
Keywords: refractive index anisotropy dispersion, liquid crystals, hardware complex, voltage-contrast characteristic.
