A construction of the measurement cuvette and dependence of the refractive index of an immersion liquid on its parameters is discussed. The dependence of the refractive index of α-bromonaphtalene on temperature for λ = 0.6328 μm is described. A measuring method of the refractive index profile of gradient-index elements is presented.}, title={Characterization of the refractive index in gradient-index elements}, type={artykuł}, keywords={optyka, GRIN lenses measurements, refractive index measurement, GRIN glass}, }
