Abstract: Of fundamental importance in the fluctuation theory of second order phase transitions is the deviation of the correlation function from the mean field Ornstein-Zernike approximation, as measured by the critical exponent η. In this note it is demonstrated how measurements of the temperature dependence of the turbidity of a fluid very close to its critical point can lead to a determination of η. Applied to a pure fluid, this technique will require a microgravity environment.
