Radial Polarizer !

(Not a circular polarizer)
The ZPol turns any linear polarized laser into Radial or
Azimuthal polarized light. This Radial polarized light can in
turn be made to generate Z Polarization, or polarization in
the direction of light propagation.

Z polarization enables one to obtain 3D orientation of molecules and crystals.

Z Polarization is produced by a combination of ZPol and a
high NA lens. The focal spot given by the lens has strong
Z polarized light resulting from interference of radial polarization at the geometrical focus. In other words you have
a strong longitudinal electric field that oscillates along the
optical axis at the center of the focus spot.
With Azimuthal polarization a strong longitudinal magnetic
field is observed that oscillates along the optical axis at the
center of the focus spot.
