A method for the quantitative determination of the laser beam deflection on passage through an electro‐optic modulator is presented. The hardware used to determine simultaneously the beam polarization parameters and deflections is described, and a procedure for minimizing these deflections is outlined. Examples of artifacts caused by the motion of the laser beam in the observation of Raman optical activity are presented.
