 The sound velocity, formula_26, depends on the angle α, such that,

formula_44 and formula_45 are the sound velocities along the axes [110] and [001], consecutively.The value of formula_46 is determined by the angles formula_32 and formula_30,

The angle formula_34 between the diffracted and non-diffracted beams defines the view field of the filter; it can be calculated from the formula,

Input light need not be polarized for a non-collinear design.Unpolarized input light is scattered into orthogonally polarized beams separated by the scattering angle for the particular design and wavelength.
