Quarter Wave & Half Wave Retarder Optical Filters
API wave retarder filters are used in applications such as emissive displays, camera filters, sensor applications, and 3D filters. The added benefit of the glass substrate is improved clarity, resolution, durability, environmental stability, and improved performance (with anti-reflective coatings). API quarter wave and half wave retarders are chromatic single layer polycarbonate films for great performance and clarity.
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.
