S-waveplate is a space-variant retarder that converts linear polarization to radial or azimuthal polarization. The product is UNIQUE for its HIGH DAMAGE THRESHOLD. Unique results are achieved through the formation of subwavelength nanogratings inside fused silica glass.
Custom space-variant waveplates are space-variant retardance plates which enables tailored control of spatial polarization with retardance and predefined patterns of slow axis.
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. /Photo: Courtesy of EKSPLA/
