Volumetric PSFs

The extent of the Bessel-Gauss PSF generated by a linearly-polarized annular pupil function varies with the waist of the annulus. Annular pupils of various waists generate Bessel-Gauss beams with various axial extents

Vectorial pupils

Special foci can be created from inhomogenously-polarized pupils. The following is a model of a tightly focused and radially polarized Laguerre-Gaussian beam.
