Popis: A simple method for measuring the refractive index of liquids that fill thin-wall cylindrical cells of any diameter is described. The method is based on the light-refraction phenomenon in cylindrical lenses and is implemented using a system of lines that are regularly positioned in a plane and are observed in monochromatic light through a liquid-filled cylinder. Images of lines are turned relative to the initial orientation, and the rotation angle is unambiguously related to the refractive index of the liquid.
