Z Polarizer

◦Useful for various application such as laser scanning microscopy, tip-enhanced near-field microscopy, Raman microscopy, laser trapping, and laser processing.
◦Z-polarizer is comprised of four-segment waveplate with the different orientation of the optical axis of each of the segmented waveplate so you can generate both radial polarization and azimuth polarization.
◦In combination with condenser lens, Z-polarizer can produce a field of the light beam with a large electric field component in the z-direction (radial polarization). It can also produce azimuthal polarization by choice, a light collecting field that the z component of the electric field to zero.
