title: Beam refraction and displacement in a differential refractometer with an absorbing sample.
abstract: The transmission of an optical beam through the compound cell of a differential refractometer with an absorbing sample is analyzed. Formulas for the lateral shift and the deflection angle of the transmitted optical beam for a complex refractive-index difference are obtained.
