Polymer waveplates (retarders)

Share this on social media:

Edmund Optics has introduced new polymer waveplates (retarders). Designed for transmitting light while modifying its optical polarisation state, these versatile polymer waveplate (retarders) do not attenuate, deviate or displace the beam.

Polymer waveplate (retarders) offer a durable, low-cost alternative to quartz waveplates. They feature a thin birefringent polymer film that is layered between two glass windows, which increases durability and ease of handling. Available in ¼λ and ½λ retardance, polymer waveplate (retarders) are specifically designed to act as true zero-order waveplates. They provide excellent angular field of view and lower sensitivity to incidence angles than comparable quartz waveplates. They offer stable performance over wavelength shift and wide angles of incidence.

Polymer waveplate (retarders) are available with multiple wavelengths or achromatic designs and identify the fast axis, marked on the edge of the glass, for convenience and ease of use. Models are available in 405nm, 488nm, 532nm, 560nm, 633nm and 650nm wavelengths in ¼ wave or ½ wave varieties. A ¼ wave Polymer Achromatic Waveplate offers a 450-600nm wavelength range.
