Introductions
The LCP vortex retarders has polarization-dependent optical properties. Depending on the different polarization states of the incident light beam, liquid crystal polymers vortex retarders can be used to generate vector polarized light beams or vortex light beams with helical phase wavefronts, converting TEM00 Gaussian light beams into “hollow hole-type” hollow intensity distribution (for more optical properties, please refer to the technical description). Compared to traditional light field control methods, the zero-order vortex half-wave retarders has the advantages of high efficiency, stability, simple operation, and specific function; its true zero-order feature also helps achieve lower wavelength sensitivity, higher temperature stability, and a larger incident angle range.
