Hangzhou Shalom EO supplies polymer true zero-order half 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/2 phase shift, and are excellent for rotation of the linear polarization. In comparison with crystal half waveplates, polymer half waveplates allow wider angular acceptance and the true zero order design permits broad spectrum applications.
