In this work we demonstrate a simple setup to generate and measure arbitraryvector beams that are tightly focused. The vector beams are created with aspatial light modulator and focused with a microscope objective with aneffective numerical aperture of 1.2. The transverse polarization components($E_x$, $E_y$) of the tightly focused vector beams are measured with 3 stepinterferometry. The axial component $E_z$ is reconstructed using the transversefields with Gauss law. We measure beams with the following polarization states:circular, radial, azimuthal, spiral, flower and spider web.
