Acrylic Quarter Wave, Half Wave, and Full Wave Plates
API quarter wave, half wave, and full wave plates are single layer polycarbonate films for great performance and clarity. A wave plate is a birefringent material that alters (retards) the polarization state or phase of light traveling through it.
Our wave retarders feature uniform birefringence, very low haze, good environmental stability and excellent wide-angle view performance. API can laminate quarter wave retarders in 560nm (140nm OPD) and half wave retarders in 560nm (280nm OPD) for increased durability and optical performance.
