We propose a method for filtering convergent light beams with arbitrary polarization. For this purpose, a tandem of similar acousto-optic tunable filters was applied. Owing to the special mutual orientation of the cells, two coincident beams with ordinary and extraordinary polarizations were diffracted by the first crystal and the second crystal, respectively.
