S-waveplate (Radial Polarization Converter)

Altechna

S-waveplate is a super-structured waveplate which converts incident linear polarization to radial or azimuthal polarization. S-waveplate can also be used to convert incident circular polarization to a beam carrying optical angular momentum. Product is unique for its high damage threshold at least 10 times exceeding alternative liquid crystal devices. S-waveplate is fabricated inside UVFS bulk. Features - Converts linear polarization to radial or azimuthal polarization - Generates optical vortex (if incident polarization is circular) - High damage threshold - 50-90% transmission (dependable on wavelength, AR coatings applicable) - Large aperture possible (up to 15 mm; standard 6 mm) - No segment stitching
