Hangzhou Shalom EO supplies polymer true zero-order quarter waveplates consisting of a liquid crystal polymer thin film laminated between two UV Fused Silica windows. The polymer true zero order quarter waveplates introduce a λ/4 phase shift, and are excellent for conversion between linear and circular polarization, in comparison with crystal quarter waveplates, polymer quarter waveplates allow wider angular acceptance and the true zero order design permits broad spectrum applications.
