Although the Brewster's angle itself is not critical, skewness of the two angle faces with respect to the polarization vector will cause high cavity losses.

A method for reducing the strong Rayleigh line in the spectrometer by making the polarization vector parallel to the spectrometer axis is described in Reference 4. This is useful when viewing depolarized (e.g., rotational) Raman scattering close to the exciting line. Note that this method should not be used for examining strongly polarized Raman lines.
