S-waveplate (Radial Polarization Converter)

S-waveplate is a super-structured space-variant waveplate which converts linear polarization to azimuthal or radial polarization, and circular polarization to optical vortex.

Custom Space-Variant Waveplates

Custom space-variant waveplates are space-variant retardance plates which enables tailored control of spatial polarization with retardance and predefined patterns of slow axis.

Space-Variant Waveplate for Flat-Top Conversion

Combination of a space-variant waveplate and a polarizer acts as a space-variant transmission filter and can be used to transform an initially Gaussian beam to a flat-top beam.
