We analytically and numerically investigate formation of cylindrical vector beams by birefringent crystal in accordance with two schemes: with one combined focus, and with two focuses. In the case with two focuses at presence of a vortical phase in incident beam with circular polarization in one of focuses the radially-polarized distribution is generated, and in another - azimuthally-polarized. The results are generalized on a case of formation radially- and аzimuthally-polarized laser beams of the higher orders. Experiments with a crystal of Icelandic spar confirm results of simulations.
