Radial Polarisation Converter, S-waveplate, 515nm ±20nm

Manufacturer's part number :


Manufacturer Altechna


Description :

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.
