S-waveplate (Radial Polarization Converter)

More Views

S-waveplate is a super-structured waveplate which converts linear polarization to radial or azimuthal polarization. Radial polarization enables focusing laser beam into a smaller spot size. Radial and azimuth polarizations allows achieving the same machining properties in all directions. It is also applicable in optical tweezers and microscopy.

Description

Details

S-waveplate is a super-structured waveplate which converts linear polarization to radial or azimuthal polarization. Production of S-waveplate is based on unique laser nano-structuring technique developed by prof. Peter G. Kazansky group from Optoelectronics Research Centre at Southampton University.

Radial polarization enables focusing laser beam into a smaller spot size. Radially polarized beam improves processing quality, reducing the distortions affecting the edge quality of the machined structures. Moreover, radially polarized beam is more efficient at drilling and cutting high-aspect-ratio features. It is also applicable in optical tweezers, laser micromachining, STED microscopy, two-photon excitation fluorescence microscopy.
