A method utilizing rotation effect of the quartz crystal to generate vectorial polarized beam is proposed. The quartz crystal is divided into twelve sectors with the same angle, and the thickness of the individual sector is designed with specific value. According the property of the crystal, the polarization direction of the incoming planar polarized beam is changed with different rotation angle in different sectors. So the beam with spatially different polarization is formed. Furthermore the irradiance distribution near the focus with a high-numerical aperture lens is also calculated with two-dimensional Simpson calculus(ZDSC) method. It is found that the focusing property of the vector beam is very similar to that of the cylindrically polarized beam. The method can be used to generate cylindrically polarized beam to meet the practical application needs.
