Acrylic Quarter Wave, Half Wave & Full Wave Plates
API quarter wave, half wave, and full waveplates (retarders) are single layer polycarbonate films for great performance and clarity. A waveplate 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 also laminates our polymer wave retarder films to glass for increased durability and optical performance.
- 1/4 wave, 1/2 wave and full wave
- Excellent clarity and uniform birefringence
- Custom shapes and sizes
- High performance near achromatic quarter wave plate available
